I frequently run into a very annoying problem when rendering scenes with cycles where I use an environment texture. Upon rendering the animation, Blender sometimes looses the environment texture, displays it as pink and renders the whole frame unusable. The render then stops, I have to manually save, close, restart the program and continue rendering. It happens about 3-4 times in 300 frames during a 6 hour rendertime. It happens on both CPU and GPU renderers and happens on different computers, even different users (a friend of mine has the same problem). The problem occurs in Blender 2.76 and 2.77.
The GPU renderer outputs this error message: cuda error at cumoduleload: file not found I tried relocating the texture to a SSD, a different HDD, the projects directory, nothing helps.
Any ideas? Thanks for the help :)
