WebMar 13, 2024 · Yes, you need to use Transparent BSDF shader as you did or Alpha value in Principled BSDF, but you also need to choose a type of transperency in material settings, for example Alpha Blend instead of Opaque. This reply was modified 3 years, 9 months ago by Mikhail Luzyanin . Co-founder and lead graphics specialist at Soft8Soft. WebBSSRDF implementations must pass the current (outgoing) surface interaction as well as the index of refraction of the scattering medium to the base class constructor. There is thus an implicit assumption that the index of refraction is constant throughout the medium, which is a widely used assumption in BSSRDF models. WebApr 13, 2024 · The Glass BSDF is used to add a Glass-like shader mixing refraction and reflection at grazing angles. Like the transparent shader, only pure white will make it transparent. The glass shader tends to cause noise due to caustics. Since the Cycles path tracing integrator is not very good at rendering caustics, it helps to combine this with a ... shower tub floor mat
