Will fire and smoke on GPU be supported in 2.75? Are there any infos about the roadmap regarding this issue?
I found that if you want a fast facsimile is to use OpenGL render (not in the render menu, rather a the top of the interface). I rendered 100 frames in about a minute on a black background then "add" layer composition to the GPU smokeless animation. Looks really good.
Version 2.77 will support GPU rendering of Fire & Smoke : http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.77/Cycles
- Smoke/Fire and Point Density support on GPU.
In previous versions there is no support for fire and smoke on Cycles GPU, it just renders invisible or black .
