Description

Port the work from Tangent Animation to the latest Cycles.

There are a few parts to this:

  • Use OIIO texture cache in SVM
  • Reduced quality lookups on indirect bounces
  • Improve ray differentials in BSDF to ensure higher MIP levels are used
  • Preserve ray differentials in SVM
  • .tx file workflow, including automated generation
  • Bundle maketx with Blender
  • Optimize texture lookups by randomly sampling one of two MIP levels instead of interpolating between them

For GPU rendering, the OptiX SDK has code that we could adapt. Potentially this could be used for both CPU and GPU rendering.

Please do consider add a option in

preference->file Paths

to allow setting custom path for the generated .tx files!
I used to use arnold and have .tx files in my cloud drive which are all over the place and I hate that!

Hey @Dalai Felinto (dfelinto) !

Sorry to bother you, is there any news about that? I hope you're fine
Can you tell us more?
Do you plan to put someone in the near future to develop this feature?

This feature is a must have for production and big project, but it's also completly usefull for small project and render optimisation

Cheers !

I agree with Quentin. This task is 3 years old and it's one of the most important feature for a renderer. Badly need it

Would be great to get an update on this please. It's a super important feature to have. You won't find a rendering in the whole VFX industry that doesn't use this.
