Hi everyone,

I was wondering how to put several objects into the same SSS set so when subsurface scattering calculation happen all object from the same set are take into account ?
I have several object that I can't/don't want fuse together. Is there a feature that allow that in Karma ?

a bit like this : ( look at the bottom of the page, the gum and teeth )

If the feature exist, could you point me into the right direction ?

Currently you can't, but it's on the feature list for H21.

I can't see it on the list from the H21 sneak peak but I hope it is true !

Added support for SSS tracesets to allow SSS light paths to travel across mesh that share the common tracset. This can be used to remove discontinuity artifacts when a character with SSS is split into different parts. Note that there’s a limit of four tracesets per scene with Karma XPU.
