Is there an alternative to point density for rendering with GPU? Finally working with some clouds. Rendering is horribly slow with my i5 CPU, would be much better with a GTX 970, but if I try that then shaders that use point density no longer work. Is there a good alternative to point density that is renderable with a GPU in Cycles?
As of version 2.77, Point Density rendering is now supported on GPU. Additional color capabilities should appear in 2.78.
