I am working on a simple smoke sim using cycles, and was rendering fine on the GPU. Suddenly, blender crashes and when I reopen blender the GPU no longer renders smoke.
I have tried opening an older version of the project, and still the GPU does not render the smoke. Same story after restarting computer, emptying cache, re baking the sim, and updating GPU drivers.
The simulation still renders fine on the CPU, and all the other objects/materials render fine with the GPU.
This has now happened to me on multiple projects, and is very frustrating as blender crashes all the time while rendering decent fire animations on my cpu. I'm not sure why that is.
I am running Blender 2.78, and here are my computer specs:
CPU - Intel i7 - 5930K CPU @ 3.50GHz 32 GB RAM GPU - GeForce GTX 980 Ti (x2)
Running Win10 pro 64 bit
And, in blender under user preferences I have the compute device set to: CUDA GeForce GTX 980 Ti (2x)
And have the device set to "GPU Compute" in the render tab.
Any thoughts, or anyone experience a similar problem?
