Please correct me if I'm wrong, but doesn't previous version render a black object,
when I assigned material with additive layer or SSS material ?

Here are results with 4.0.0.8, enviroment is lit by ...\hdri\hdrmaps\hdrmaps-com-E018.exr (in MR root directory)
CPU additive layer Rg=0 R0,R90=0 0 0 Nd=1.51


GPU additive layer Rg=0 R0,R90=0 0 0 Nd=1.51


GPU Rubber Blue Translucent preset

Looks like additive layers and SSS is now working in GPU

I am playing with additive layers now and on both the GPU and CPU Fire my red plastic starts as orange and becomes red the longer it renders. Is this normal? I havce never noticed that before.

CPU render (not fire) its ok
