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

Vuk Gardašević (lijenstina) added a comment to T50460: Cycles cull option ui problem.

I don't see how this is an underlying issue with the layout engine. Using a .active or .disabled tag, assigned to a certain layout block will affect all of its assigned properties. So using two different UI blocks is a proper fix.

Will commit a fix based on Ronnys suggestion.

Vuk Gardašević (lijenstina) added a project to T50460: Cycles cull option ui problem: User Interface.

The behavior of .active with rows that share the same parent can be an issue that can show up elsewhere in the UI, so adding user interface tag too.

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…

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.

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?
