Render (Geometry, texture, particle data) Caching for animation is needed for Cycles

Cycles is lacking any BVH/textures precaching that would allow user to save precomputation time for each frame during rendering process of animation. With no animation aside of camera, no geometry change, no textures change it still takes time for bvh calculations and etc. When using renderfarm the caching process became the bottleneck of the speedups you can get.

I've tried Octane recently and I've been blown away by the speedup this thing could give to my pipeline. Now renderfarms actually makes sense. Obviously it's a compex matter, otherwise it would be implemented already. Octane allow automatic or manual approach for caching, movable, static or demormable objects been treating differently.

I hope it'd bring attention to the feature mentioned and this task will be added to the Render module developer.blender.org/T66305 imgur.com/N1RZlmk
