Re: FBX export of objects with Luxcore materials

Thanks for your reply. I also suspect that.

No problem, I was just wondering.

FBX export of objects with Luxcore materials

Hi, I'm wondering: If I export objects with Luxcore materials to an FBX file from Blender, will the materials be properly exported? In other words: if the exported FBX file is opened in a different application, will the diffuse colors and maybe other material properties be intact, or is Blender's FB...

Re: Micro-roughness

Thanks. I've read all posts. Concluding, it's more of a fake effect that would need an angle-dependent falloff implementation. I would welcome a falloff node though, for angle-based coloring and other effects. Looking at Octane, it should not get in the way of realistic material behaviour.

Micro-roughness

Hi,

I'm wondering: does Luxcore have this effect incorporated in its shaders?

It looks like a feature that could improve reflection behaviour realism.

Re: Disney BRDF material

That'd be great. SSS is one of the few things in Luxcore that are hard to get right.

Re: Disney BRDF material

I had never used the Disney material in Luxcore, and tried it today.

I don't see a noticeable difference between an SSS value of 0 and 1, is that correct? Is a volume node maybe still necessary for SSS?

It would be great if the SSS could be similar to the Cycles Principled shader's SSS.

Re: Sub-Surface Scattering

Haha, yes, after (de)activating all kinds of caches and rendering modes, I found out that the specular difference is simply a matter of switching between GPU and CPU, where the CPU result looks considerably better.

You can see the difference in this post.

Re: Sub-Surface Scattering

Thanks, I thought so too.

BYOB already has my pumpkin scene, so he can check it out. If his findings are not the same, it might be caused by my hardware configuration.
