After getting the Caustics branch up and running, I gotta say, its pretty awesome!
The caustics stuff is really cool, but I love the new RtGi.
All the extra settings are great and the new denoiser is fantastic.
Final gather looks so much closer to Brute force now and I can really only see the noise on untextured surfaces in partial soft shadow.
Also being able to have ray traced shading, refraction and absorption in reflections is fantastic, I do interior kitchen and bathroom renders and this improves the look of mirrors quite a bit.
Like RTXGi the caustics stuff only works with low level lighting values, not physically correct values, so hopefully this can be addressed, but it is not a deal breaker, just an inconvenience.
Is there any timeline for when these new caustics and RT features will become part of the main branch?
