Is there any limitations in mantra's PBR engine on translucency ? In any other modes (MP, RT) translucency works just fine, but when i switch into PBR mode everything that should be translucent becomes black. Need to say that i've tried every standard shader with translucency that comes with Houdini. The same result. Closer look into shader network doesn't make situation clearer… Every BSDF output connected to the right places, everything looks just fine.
In general translucency is a sum of diffuse(N) and diffuse(-N) component. Right? So it looks like when you flip normal N to get backlight diffuse component, BPR ignores it ! It get the original one N ! I think this might be hardcoded somewhere inside Mantra…
Is there any workaround to get translucecy working in PBR ?
Million times thank you !
