Is the Diffuse reflection of OmniSurfaceBase using the Oren Nyar model?
@zzz_zhang666 based on the doc, it seems like the diffuse roughness is - Omniverse Materials — materials-and-rendering latest documentation
@Simplychenable My question is here. The meaning of ‘Diffuse Roughness’ is that when the roughness is 0.0, it is a Lambertian model, while when the roughness is not 0.0, it is an Oren Nyar. Can I understand it this way?
that’s my understanding, yes. and the cap would be at 1.0. so not an on/off situation but you are allowed to dial the coefficient. per wiki:
@Simplychenable Thank you. Your response is always great
