Microfacet Roughness Workaround?
Posted: Sun Aug 17, 2025 12:05 pm
Hi,
I ran some render tests in LuxCore for nested dielectrics and noticed that the rough ice cubes in the scene get really dark. As far as I looked into it this is because of improper energy conservation due the lack of microfacet roughness calculation. Now my question is if there is a known workaround for this kind of material?
