Blender Cycles: OpenCL now is on par with CUDA

Cycles has a split OpenCL kernel since Blender release 2.75. It's an alternative approach to what is used on CPU (so called megakernel). 
The idea behind splitting the kernel is to have multiple smaller kernels which are not only simpler and faster to compile, but also have better performance. 
Initial split kernel patch was done by AMD. Further work was also funded by AMD. 
The OpenCL Split Kernel now supports nearly all features. Only Correlated multi jitter is missing. 
Baking works, but uses the mega kernel. Volumetrics, SSS, Branched path tracing, HDR lightning and Denoising are fully supported. 
With current drivers, all production files from the official cycles benchmark pack, including the huge one from Gooseberry, render now pretty fast.

Blender3D / How to create procedural fire shaders



Learn how to set up a convincing fire shader using nodes.
iscream writes:
HI every one, once again it's me Iscream, I've just finished to write the part two of my tutorial on "how to make fire shader" without sim, and really fast to render. It covers the base of my workflow on UV and how to arrange node groups.
There is a file with the result of the tutorial at the end of part 2. but you should do it yourself really :)
Before doing part 3, I would like some feedback from beginners to improve it, and suggestions for the direction to take, should it be sparks, smoke, heat distortion, candle flame, fire camp, just say me ...
You can also suggest unrelated stuff so I can start to think about it (here or in the articles comments)

Tutorial on PBR Texture Creation Workflow in Blender



This is an experimental PBR texture creation workflow I am developing for advance texturing in Blender which can be cross platform in game engines and also in VFX environment.

I am trying to hack the micro bump more and will let you know if something can be done more accurately. If you have any suggestion please let me know. Thanks.

Blender 2.75a update release

The Blender 2.75a bug fix release addresses some urgent issues that popped in in the recently released Blender 2.75.


Ton writes:
A couple of bug fixes were important enough to not leave in the 2.75 release, even though the next release is already expected in 5 weeks.
If you don't like boring bug fix logs, this is good to know at least:
  • Game Engine would crash for Objects using velocity clamping
  • Browsing render passes in Blender crashed.
For the rest, the full list.
Download it here: http://www.blender.org/download/
***

The two main fixes to know for this release are:
  • Game Engine would crash for Objects using velocity clamping
  • Browsing render passes in Blender crashed.
The more technical info:
Changes from revision 295d0c52a26730edc6d4ed1276e4051cce006be5 to 5af1daa2dc85adcabc057c1f28ca29163fae3d00, inclusive (master branch).

  • Fix vertex-slide regression with rotated objects (rBc702dab)
  • Fix vertex-slide helper-line scale (rB51e9a81)
  • Fix Multi-View UI: convergence is only useless for the parallel camera (toe-in still uses it) (rB80f344f)
  • Fix Keyframe indicators for NLA Strip properties fails if the AnimData has an active action (rBd96842b)
  • Correct --help message (rBd3709f4

The Cycles Shader Encyclopedia

The Cycles Shader Encyclopedia

Greg Zaal has published an extensive overview of Cycles Shaders on Blender Guru.

Find Cycles Nodes a little confusing? You’re not alone.
Whilst Cycles Nodes offer almost you limitless control over a materials, many users struggle to understand it’s labyrinth of options.

Which is why this article dares to do the impossible: explain every Cycles shader in easy to understand, plain English.
Enjoy! -Greg Zaal

    • Two quick access pie menus were added
  • Graph Editor:
    • Revised the set of operators for showing/hiding curves from the keyframe area
    • Circle selection for Curves was added
  • And more!


Add-ons

  • Collada Importer:
    • Importing rigs previously caused problems with leaf bones (end bone of a bone chain) so a fix was created for that.
    • Added an experimental bonechain Finder to predict the longest possible chains of connected bones.
  • The FBX Add-on now uses some advanced handling/tweaking options for importing and exporting armatures
  • The Copy and Paste Add-on is now using version 2.0
To Add-on developers: Some changes were made to the Python API, make sure to check them out and update your Add-ons if necessary!

Blender 2.71 Smoke and Fire in Cycles Demos #2



Gottfried Hofmann of BlenderDiplom shares some impressive fire and smoke simulation tests rendered in Cycles.

Gottfried Hofmann writes:
I did another series of smoke and fire tests with Blender 2.71 and Cycles. This time I used the final version which had many bugs fixed and some performance improvements which allowed me to render the scenes in FullHD. Render times where still kinda high, though...

Blender 2.66 released


Новое в этом релизе:
  • Динамическая топология в режиме скульпта. Этот режим подразделяет сетку при необходимости, что позволяет делать сложные формы без ручного добавления деталей к сетке;
  • Копирование и вставка объектов по ctrl+C/ctrl+V;
  • Bevel теперь можно применить и к вершинам;
  • Модификатор UV Warp - позволяет модифицировать UV-карты с помощью объектов или костей;
  • Модификаторы Laplacian Smooth Modifier и Shape Enhanced - позволяют снизить «шум» сетки, также с их помощью можно сделать объекты карикатурными;
  • Физический движок Bullet теперь работает не только в игровом движке, но и в основном редакторе и анимации, что даёт лучший контроль над результатом симуляции. Это позволяет также задействовать, например, Rigid body;
  • Один из последних и самых больших гвоздей в крышку гроба традиционного Blender Internal renderer - поддержка волос в Cycles renderer. Теперь толщина и форма волос задаются непосредственно в настройках системы частиц без необходимости создавать отдельный объект;
  • Другие возможности и исправления ошибок.
Традиционно программа доступна как для Linux, так и для Windows, Mac OS X и FreeBSD.
