Added variance clamping support to BIDIRCPU

Post by Dade » Sat Apr 07, 2018 9:11 pm

I have added the support for variance clamping to BIDIRCPU. It is enabled with the usual property "path.clamping.variance.maxvalue". This is a rendering with PATHCPU and 300 samples per pixel and the (heavy) variance clamping enabled:

Same rendering with BIDIRCPU and the (heavy) variance clamping enabled:

And this with BIDIRCPU and the (heavy) variance clamping disabled:

BIDIRCPU+Variance Clamping is clearly working well :D

Can you post fully converged Bidir without clamping and with clamp so we see how much detail is lost or not ?

Ok, going to take some time for renderings.

I added support for it in the Blender addon.
(However you have to wait for the next release or compile yourself if you want to try it)
