Endringer for v2.80 - v2.81

The much anticipated update of the Blender 2.80 milestone is here! With over a thousand fixes and several important updates that were planned for the 2.8 series. Most notable are the sculpting tools overhaul, support for NVIDIA RTX ray tracing in Cycles, Intel Open Image denoising, a better outliner, a new file browser and much more.
Sculpting Rethought
A complete overhaul of the sculpting workflow.
Read more
New Cursor & Brush Settings
Auto Masking
Assigns a factor to each vertex before starting the stroke. Topology automasking affects only vertices connected to the active vertex.
World Spacing
Keep an even distance between stroke points in 3D space. Great for sculpting near the edges.
Grab Active Vertex
Snaps the maximum strength of the grab brush to the highlighted active vertex, making it easier to manipulate low poly models or meshes with subdivision surfaces.
Normal Radius
Control how sensitive the sculpt normal direction is to the underlying surface.
New Cursor
Dynamic Mesh Preview
The cursor now is aligned to the surface normal, displays symmetry and a preview curve fall-off.
Masking
Mask Filter
Modifies the whole paint mask. In includes multiple operations like smooth, grow or contrast accessible from a pie menu.
Dirty Mask Generator
Similar to Dirty Vertex Colors, but it generates a paint mask. It can be used to mask cavities in the sculpt.
Mask Expand
Creates a mask from the active vertex to the vertex under the cursor based on topology or mesh curvature.
Mask Extract
Extracts the paint mask to a new mesh object. It can extract the paint mask creating a boundary loop in the geometry, making it ready for adding a subdivision surface modifier.
Mask Expand by Curvature
Mask Extract
New Tools
Pose Brush
Pose a model simulating an armature-like deformation. The pivot point for rotation is calculated automatically based on the radius of the brush and the topology of the model.
Elastic Deform Brush
Based on Pixar's paper Regularized Kelvinlets:
Sculpting Brushes based on Fundamental Solutions of Elasticity, this tool lets you grab, biscale grab, triscale grab, scale and twist operations while preserving volume.
Translate, Rotate, Scale
Use the familiar transform tools now also during sculpt. Transforming around a pivot point and taking into account symmetry.
Draw Sharp Brush
Similar to the draw brush, but it deforms the mesh from the original coordinates. When used with the sharper curve presets it has a much more pleasant crease/cut behavior than any of the other brushes. It is useful for creating cloth wrinkles, stylized hair or hard surface edges.
Mesh Filter Tool
Applies a deformation to all vertices in the mesh at the same time. It includes multiple deformation modes and the option to lock the deformation axis.
Elastic Deform: Grab
Elastic Deform: Scale
Transform Tools in Sculpt Mode
Remeshing
Blender 2.81 now ships with two new ways to remesh your models, a fast one based on volumes and another one preserving quads.
Read more
OpenVDB Voxel
Quickly create a new quad mesh based on the volume of the mesh. It is particularly useful for sculpting, to generate a good topology when blocking shapes, as an alternative to dynamic topology without the performance cost of continuous updates.
QuadriFlow
Creates a quad mesh with few poles and edge loops following the curvature of the surface. This method is relatively slow but generates higher quality for final topology.
NVIDIA RTX Support
Cycles now has experimental support for rendering with hardware-accelerated raytracing on NVIDIA RTX graphics cards. It’s On.
The OptiX backend was contributed by NVIDIA.
Intel® Open Image Denoise
A new Denoise node was added in the compositor, to denoise renders using OpenImageDenoise.
Compared to the existing denoiser, it works better with more complex materials like glass, and suffers less from splotchy artifacts. It also gives better results with very low numbers of samples, which can be used for quick previews.
Read more
Cycles
Not everything is EEVEE these days! Cycles got new and improved nodes, a new denoiser, adaptive subdivision stitching, custom HDRI picking from the viewport, NVIDIA RTX support and optimizations all over the board.

Smart Pre-selection
Library Overrides
Library Overrides is the new system designed to replace and supersede Proxies.
Most types of linked data-blocks can be overridden, and the properties of those overrides can then be edited.When the library data change, unmodified properties of the override one will be updated accordingly.
Compared to proxies, library overrides support:
Multiple independent overrides of the same linked data (i.e. link a character once, instance it multiple times!).
Adding new modifiers and constraints, anywhere in the stack.
Recursively chaining overrides (i.e. link and override overrides from another library file, etc.).
Viewport
The viewport and workbench also got improvements in this release.
Read more

Edit & Grade
What You See Is What You Need
Thanks to the new modern 3D viewport you will be able to display a scene optimized for the task you are performing. A new Workbench render engine was designed for getting work done in the viewport, supporting tasks like scene layout, modeling and sculpting. The engine also feature overlays, providing fine control over which utilities are visible on top of the render.
Overlays also work on top of Eevee and Cycles render previews, so you can edit and paint the scene with full shading.

Random Colors
Colored Wireframes
Look Dev
Tools & Gizmos
The 3D viewport and UV editor have new interactive tools and gizmos, along with a new toolbar. These make it easier to for new users to start using Blender, and for existing users to discover and use tools that previously required obscure key combinations.
Besides gizmos for tools, various elements like lights, camera, and the compositing backdrop image now have handles to adjust their shape or other attributes.
Intuitive Widgets
A set of simple yet functional controls will make 3D interaction fun again.
Toolbars
The new contextual toolbars enable you to quickly access and discover the right tool for the job.
Real Time
Eevee is a new physically based real-time renderer. It works both as a renderer for final frames, and as the engine driving Blender’s realtime viewport for creating assets.
It has advanced features such as volumetrics, screen-space reflections and refractions, subsurface scattering, soft and contact shadows, depth of field, camera motion blur and bloom.
Read more
Eevee materials are created using the same shader nodes as Cycles, making it easy to render existing scenes. For Cycles users, this compatibility makes Eevee work great as a realtime preview. For game artists, the Principled BSDF is compatible with shading models used in many game engines.
2D Animation
Grease Pencil is now a full 2D drawing and animation system. This unprecedented integration of 2D tools in a 3D environment will enable you to create next-level concept art, storyboards and animations.
Read more
Grease Pencil objects are a native part of Blender, integrating with existing object selection, editing, management, and linking tools. Strokes can be organized into layers, and shaded with materials and textures. Besides a draw mode for strokes, these objects can also be edited, sculpted and weight painted similarly to meshes.
Modifiers can be used to deform, generate and color strokes. Commonly used mesh modifiers such as array, subdivide and armature deform have equivalents for strokes. Rendering effects like blur, shadows or rim lighting are also available.
Cycles
Cycles now provides industry-standard functionality such as Cryptomatte, BSDF hair and volume shading and Random Walk Subsurface scattering. Many rendering optimizations were done including combined CPU and GPU rendering, much improved OpenCL start and render time, and CUDA support for scenes that don’t fit in GPU memory.
Read more
Principled Hair BSDF
Rendering physically based hair and fur is now easier and no longer requires setting up a complex shader network.
Cryptomatte
Cryptomatte is a standard to efficiently create mattes for compositing. Cycles outputs the required passes, which can be used in the Blender compositor or any compositor with Cryptomatte support.
Random Walk Subsurface Scattering
The new Random Walk subsurface scattering method provides more accurate results for thin and curved objects.
Subdivision and Displacement
New offscreen dicing scale helps to significantly reduce memory usage, by reducing the dicing rate for objects the further they are outside of the camera view.
Cycles has been used in high-profile short and feature films, and is receiving a growing amount of contributions from the industry. The full list of improvements is available on the wiki release notes. Here are some highlights.
Principled Volume Shader
Bevel Shader
Ambient Occlusion Shader
Performance Optimizations
GPU+CPU Rendering

Endringer for v2.64a - v2.65

The Blender Foundation and online developer community is proud to present Blender 2.65. We focused on making this the most stable release in the 2.6 cycle yet, fixing over 200 bugs.
Fire simulation was added along with many improvements in smoke simulation. In Cycles, motion blur, open shading language and anisotropic shading support was added. For mesh modeling, the bevel tool was much improved, a new symmetrize mesh tool was added, and new Laplacian smooth, decimate, and triangulate modifiers are available.
2.65 release: December 10th, 2012.
Fire and Smoke
Fire simulation was added to the Smoke Simulator. The domain received major updates to improve performance and usability. Smoke can be emitted from mesh surfaces, without the need for a particle system. A smoke flow force field was added to improve interaction with other simulations. Colored smoke simulation and mixing is possible and the interaction of smoke with collision objects has been improved.
Mesh Modeling
The bevel tool now includes rounding and was otherwise much improved, preserving the requested bevel width more evenly and generating better topology. A new symmetrize tool was added to make mesh topology and data symmetric.
More Features
New features include: a tool transfer vertex weights from one mesh to another, antialiased viewport drawing, connected proportional editing in UV editor, improved DPX file read and write, more control over curve taper, collision masks in the game engine and improved camera title safe drawing.
Bug fixes
In addition to the new features, over 200 bugs that existed in previous releases have been fixed.
Cycles Render
Support for writing custom shaders in the Open Shading Language is now available. Motion blur rendering was also added, to make moving objects and cameras appear blurry. There is also an anisotropic shading node, and BSDF nodes can now have different normals, which can be set using the new bump and normal map nodes.
Modifiers
The decimator was rewritten, and now preserves UV's and vertex colors, has an un-subdivide and a mode to dissolve vertices to create planar n-gons. A new laplacian smooth modifier can reduce noise or smooth the mesh while preserving edges and volume. A triangulate modifier was also added, which can be useful for creating game assets with baked normal maps.
Addons
UV texture to vertex color baking was added, the PDB atomic visualization addon was improved, and film response curves were added for the RGB Curves node in the compositor.

Endringer for v2.63a - v2.64 RC 2

Mask Editor
Masks can now be created in the image and movie clip editor. They can be used in compositing to define areas of influence for nodes, block out unwanted objects, or help with green screen keying among other things. A mask datablock was added, consisting of splines that can be drawn and edited with the usual tools. Feathering can be controlled per spline point. Animation of these masks is possible with standard keyframing and drivers, but also by following motion tracks and parenting to other masks.
Motion Tracker
Motion tracking was significantly improved by adding planar tracking, and unifying the existing trackers into one Hybrid tracker with finer control. A dopesheet view for markers was added in addition to the curves view. Tripod solving is now supported, for the case where the camera only rotates without moving.
Green Screen Keying
Two new compositing nodes have been developed which are aimed at making green screen keying easier. There is now a new keying node conveniently combining various features from existing nodes along with a new keying algorithm, to makes setup much faster. There is also a keying screen node which produces a gradiented plate to deal with uneven colors of green screens.
Rendering
Compositing Nodes
A completely new compositing nodes backend was implemented. This new tiled based compositor gives quicker feedback while editing and uses less memory to support working with high resolutions. New nodes are Switch, Reroute, Bokeh Blur and Image, Box Mask, Ellipse Mask and Color Correction.
Color Management
OpenColorIO is now integrated into Blender, along with a redesign of the color management system. Previously Blender only supported radiometrically linear sRGB / BT.REC.709 chromaticities. Now many more are supported with finer control over which color transformations should be used for display, applied on renders, and used for loading and saving image files in different color spaces.
Cycles Rendering
Cycles now includes a new non-progressive integrator with finer control over sampling, tiled rendering with support for save buffers, considerably faster BVH building and multithreaded image loading, and motion vector and UV render passes. New nodes are light falloff, object info, particle info and brick texture, and image texture nodes can now do blended box mapping and handle image sequences. There is also support for fisheye camera rendering, along with various other new options.
Sequencer
Various speed improvements were implemented in the sequencer, mostly related to caching and multithreading for effect strips. These changes make color grading more interactive. Improved options for comparing the current frame to a reference frame are also available.
Modeling
Mesh Tools
Bevel and inset now are modal operator with mouse control, a wire frame tool was added to turn edges into wireframe tubes, and vertex/edge/face sorting tools were improved.
Sculpting
Sculpting has received some major improvements such has masking to control which areas of the mesh are influenced by sculpting, new brush map modes to control how textures are projected onto the model, and an input stroke averaging option to make brush strokes smoother.
Skin Modifier
The Skin modifier takes a skeleton made up of vertices and edges as input and generates a polygon skin as output, consisting mostly of quads aligned along the edges. The output is mostly quads, although some triangles will appear around intersections.
Other
Game Engine
Lamps and shadows were improved with support for variance shadow maps, shadow color, sun lamp shadows and lamp textures. Non-power of two textures and compressed textures will now load faster and use less memory. A new Character physics type was added, designed for player controlled characters for which a full dynamics simulation would give unwanted behavior.
Collada
The Collada exporter has been improved for better support of export to game engines, with more fine grained options to control which data is exported.
Small Features
Apart from the major improvements in different areas, there were lots of smaller changes such as improvements in the node editor, smoke simulation, user interface, and new tools for curves and meshes.
Bug Fixes
Lots of new features were added in this release, but it also includes lots of fixes for bugs that existed in previous releases.

Endringer for v2.63 RC 1 - v2.63

This release was focused on integrating and stabilizing the long awaited BMesh modelling system, which has full support for N-sided polygons and many new modelling tools. New tools include Dissolve, Inset, Bridge, Vertex Slide, Vertex Connect, Bevel, and improved versions of Knife, Subdivide and Rip.

Endringer for v2.62 - v2.63 RC 1

BMesh
BMesh is the new Blender mesh system with full support for N-sided polygons instead of only triangles and quads.
In particular there is a new Dissolve tool to remove vertices, edges and faces without making holes in the mesh, a new Inset tool to inset faces, and a much improved Knife tool which takes advantage of N-gons to generate clear cuts. Tools such as subdivide and loop cut will also generate clean topology because faces no longer have to be triangulated.
Cycles
Among the features added in this release are support for rendering environment maps, render layer mask layers, a shadow render pass, ambient occlusion and float precision textures.
Motion Tracker
Motion tracking got some improvements which are mostly relates on 2D stabilization and few smaller tools.
More Features
Other new features in this release include face hiding for sculpting, a compositing node to output multiple files at once or multilayer EXR files, new tools for linking and detaching nodes and more particle rotation options.
Addons
Bug Fixes
This release was mainly focused on stabilizing BMesh, but also includes 110 fixes for bugs that existed in previous releases.

Endringer for v2.61 - v2.62

The Blender Foundation and online developer community is proud to present Blender 2.62. The 2.6x series is being targeted at including all work that happened in branches or patches past years.
The Cycles render engine now has layers/passes, you can track objects inside videos now, have much better and faster boolean intersections and use great new UV Tools.

Prominent features (the cool stuff)
3D Mouse support "NDOF"
Blender is now built with support for 3D Connexion devices, for more natural control during view navigation and fly mode - r38908
Custom Keymaps
User edited keymaps now no longer override the builtin keymaps entirely, but rather save only the difference and reapply those changes. This means they can stay better in sync when the builtin keymaps change.
Keymaps in blender are now separated so Addons can properly define their own keymaps without them conflicting with user keymaps
See commit log for details - r39084
Ivy Generator (Addon)
This tools adds the ability to "grow" curves over an existing mesh with the option of adding leaves and adjusting many parameters for the final result - r2200
See: http://wiki.blender.org/index.php/Extensions:2.5/Py/Scripts/Curve/Ivy_Gen
Sapling (Addon)

Grease Scatter (Addon)
Grease scatter was used for sintel to place objects around the ally, using grease pencil lines as a guide as to where to scatter objects - r2125
Node editor enhancements
Several enhancements are done related to the node editor/compositor.
Material passes: Materials have pass-index. This pass-index can be used in the compositor to create mattes. It works the same as object passes.
Node insert: Nodes that have no connections can be inserted on a noodle. Just move the node over the noodle and release when the noodle turns orange.
Delete with reconnect: It is possible to delete a node that is connected in the tree, without loosing the connections. The node is deleted, but the links are reconnected as if the node were muted. Select a node and press CTRL-X.
Noodle curves: Some users like straight noodles, other like curved, in the user preferences the level of the curvation can be changed.
Node properties: The UI of the side panel and on the node can now be different. See the Color balance node in the side panel.

Endringer for v2.58 - v2.58a

Additions
More flexible size options for particle billboards. This adds scale factors for width and height of billboards, relative to the particle size. It's useful when the particle size is primarily used for collision and the like, so the billboard appearance can be adjusted independently. Also allows non-square billboards.
In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects. - r37760
Addon UI: button for removing addons which are installed to user/home paths - r37950
Python API:
Python application event handlers - r37795
adds bpy.app.handlers which contains lists, each for an event type:
render_pre, render_post, load_pre, load_post, save_pre, save_post

Endringer for v2.57b - v2.58

Blender 2.58 update log
The majority of work for 2.58 went into fixes with over 200 bugs fixed since last release but there are also quite a few useful additions worth checking out.
Prominent features (the cool stuff)
Warp Modifier:
Changelog 2 58 warp.png
This deformation modifier can be used to warp parts of a mesh to a new location in a very flexible way by using 2 objects to select the "from" and "to" regions with options for using a curve falloff, texture and vertex group.
Render Baking:
For high polygon models it is now possible to bake multi-resolution models using much less memory than before. There are also new bake modes: specular color, specular intensity, mirror color, mirror intensity, alpha (transparency), emission (glow)
Empty Images Display:
Changelog 2 58 empty image.png
Instead of using background images or creating meshes with materials and image texture it's now possible to assign images directly to empty objects to use as reference images. They display in all draw modes and can use object draw options like XRay to draw over other objects.
Sculpting:
Constructive modifiers (like subdivision surface, mirror and other) were supported for sculpting mode. Sculpting could be not very accurate with such modifiers enabled, so there is a new option in the toolbar to disable applying constructive modifiers in the sculpting session.
Mesh Inset (Addon):
Changelog 2 58 polygon inset.png
Mesh inset is a very useful tool with the ability to inset individual faces or a selected region.
Camera Locking:
It is now possible to move the camera using normal view port navigation by enabling "Lock Camera" in the "View" panel.

render crash when tangents are used with modifiers that remove orco coordinates
incorrect errors for panorama & orthographic camera combination
no output from texture node group
crash setting voxel data to negative resolution
crash when loading invalid voxel data and resource leak - never closing files
wrong sequencer alpha gradient
Interface:
top bar 'Add -> Mesh -> UV Sphere + Enter' - crashed
buttons with centered text truncating the first characters when there wasn't enough space
single grease pencil points drawing very large in the image editor
incorrect relative path used when opening audio
unpacking sounds with a long ID name
ambiguous operator names in the search popup
crash copying datablocks with ID Property arrays
console is not hidden when start blender
outliner objects showed "active" or "selected" in confusing ways
freedesktop icons, incorrect install location and copying SVG
sunsky presets used deprecated property names
non-functional user preference for clamping texture
smooth tangent iteration field in curve panel not responding
text editor indentation correction when when line contained ',' or ':' in a string
text editor copy/paste breaks formatting of script
Tools:
"make fur" gave errors with multiple selected objects.
mesh editmode de-selecting edge loops
dupli-extrude-cursor added wrong location when nothing selected
mesh rip tool access from menu fail
crash copying mesh, armature, lattice and metaball datablocks while in editmode
explode modifier - apply as shape impossible
add object, localview and undo error
buffer overflow with string lengths for operators that took ID names
Compositing:
'Hue Correct' composite node saturates
'Displace Node' composite node crashes Blender when connected to Z-Buffer
lens distortion composite node delivered RGBA out with alpha zero
timeline camera switch failed with compositor renderlayers
rendering non active scenes from the compositor used wrong frame
modified nodes inside edited groups not updating the view
Python:
bpy.context.object.collision access crash
crash running the transform operator from python
button input could do incorrect unit system replacements of valid python expressions
bpy.utils.blend_paths(True) crash
Game engine:
blenderplayer wasn't finding bundled python
game engine radar sensor broken
Animation:
apply scale to armature offset bone children
action/NLA editor issues with animation data context
particle group object viewport and render scale mismatch
action editor header doesn't update when entering tweakmode on NLA strips
bugs when linking particles/collision/softbody modifiers
separate armature would also separate active, unselected bone
available keying set fails in armature pose mode
b-bone doesn't resize correctly with numeric input
