Cgtrader standards / glass

asset_buil3r

Hey guys cgtrader says that for a PBR workflow I should upload at least: BaseColor Normal Metalness and Roughness. And in case of a glass material I should add an opacity map. This I don't get. I usually make my glasses with refraction maps in Vray with ior and other options, but why doesn't cgtrader ask for a material like this? Isn't the opacity channel not enough for glass' shenanigans? Thanks a bunch

I am not sure, but I think refraction maps aren't used in PBR workflow.

I don't think its compulsory advice though? you can add the info re yuor shaders in the description

Cgtrader wants materials that are renderer-agnostic. That means no refraction, only old-school opacity.

Unity apparently can import Physical Materials from FBX with all textures, see https://docs.unity3d.com/6000.0/Documentation/Manual/FBXImporter-Materials.html#:~:text=Unity%20provides%20default,from%20FBX%20files
