Documentation
Manuals for both Artists and Developers are available.

Development
Cycles is officially under the Blender Foundation umbrella, and so is developed on developer.blender.org. Source code is available either as standalone repository or as bundled into Blender sources.

To clone Cycles together with blender please consult BF Blender project.

To clone Cycles source from stadalone repository as read-only use:

git clone git://git.blender.org/cycles.git

To clone as read-write (needs ssh key):

git clone git@git.blender.org:cycles.git

Bastien Montagne (mont29) placed T50365: Objects fade when Samples > 1 up for grabs.

Cannot confirm this here, but only have CPU cycles rendering. We need @Sergey Sharybin (sergey) or some other dev from Cycles team to test that with an AMD GPU I guess…

john peterson (bliblubli) triaged T50166: Cycles - Viewport render preview stucked on the first sample - in a scene a DupliVerts objet parenting instances owned by more than one Groups as "Confirmed" priority.

Can confirm the bug, viewport render restarts indefinetly.

Thank you. Now. I can used openCL. I removed AMD catalyst 9.xx.x old version software driver and install version 15.xx.x it's worked. But i use version 16.12.2 it's not work. Thank you for suggestion.

LazyDodo (LazyDodo) lowered the priority of T50391: Blender Cycles from "Normal" to "Incomplete".

Not sure why, file is bigger now, but still missing textures,still the wrong layer selected and still no crashing behavior.. please resist changing the priority your self, it's easier for us if we manage that.

LazyDodo (LazyDodo) triaged T50391: Blender Cycles as "Incomplete" priority.

The sample file is missing some textures (be sure to use file->external data->pack into blend before uploading) , also there's nothing to render on the layer selected? When changing to the first or second layer, it renders fine with both 2.77 and 2.78a. Please provide a better test case.

Either your tile size is set too large and your device is running out of memory or this is a driver issue. Try decreasing the tile size and check that you have the latest drivers. Theres not really anything we can do to fix this, so im going to close the report.

Sergey Sharybin (sergey) reopened T50268: Cycles allows to select un supported GPUs for OpenCL as "Open".

We don't officially support Iris due to compiler limitations. We should only white-list AMD cards by default on all platforms. It should be possible to get device name on platform Apple and black-list Iris in ccl::OpenCLInfo::device_supported().

We currently do not support rendering on Intel GPUs, are you doing anything special to make the Intel GPU show up in the compute device menu?

Bastien Montagne (mont29) triaged T50307: Linking modifiers does not work properly as "Normal" priority.

@Mai Lavelle (maiself) will let you handle this one, but iirc the adaptive subdivision features is kinda hacked into subsurf modifier currently, using properties from Cycles data (and not the modifier), which make them vanish when modifier is copied? So would rather be known TODO/limitation than bug…

Bastien Montagne (mont29) triaged T50330: GPU Rendering doesn't work - Loading render kernels as "Incomplete" priority.

Please be more specific:

  • Give us your exact Blender, OS and GPU (including drivers) versions, as requested in the template!
  • Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker).
  • Try the latest build from our buildbot.
  • Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).

Alex (Alexmitchellmus) added a comment to T48399: Auto refresh on movie files does not work on frame change (Cycles).

I have stumbled onto this bug when wanting to use Blender for compositing multiple video textures. As @Thomas Beck (plasmasolutions) mentioned, activating "Property Editors" and keeping the node view open only allows one texture to be viewable at a time.
