Car Paint presets render black

[jed 431]

I just loaded the 6 car paint presets, but they all seem to render black ie invisible. Any ideas ?

Have you some source of light in your scene?  //sky, some light, physical renderer

or something for reflection?

Since material is based on reflexion channels (GGX and BSDF), source of relexion is needed imo. Try to put car into big cube with white material in luminance (invert normals)

Thanks for reply @bezo - it was a reflection thing. I had lights, but when I put a floor in, my car paint test objects all showed in render. I know about chrome-type mats needing something to reflect, but didn't realise it could apply to car paint also.

@jed  Out of curiosity, what car paint presets are you referring to? Also, ANY material with reflection has the same requirement. They all need something to reflect.

enabling the floor in this scene makes the paint appear when rendered
