Add panels to Principled BSDF node

Instead of renaming Coat to Intensity, I'm thinking maybe we can have a representative socket for the panel so that you see the value even when it's collapsed, no additional Intensity bar needed.…

Add panels to Principled BSDF node

Now that we have panel, I think the nodes should be renamed because otherwise it would be too verbose. For example all the coat-related stuff can have the coat prefix removed, and coat and be…

Refactor: Cycles: adjust microfacet lobe selection pdf by tint

Sergey said the convention in Blender is _sq, I have that in ray_sphere_intersect(), and am trying to name all the newly added variables with that suffix. But we have a lot mixed convention…

Refactor: Cycles: adjust microfacet lobe selection pdf by tint

Would be better yes! This comes from an early iteration where I was thinking r can mean both reflection and refraction, but the reflection angle is not really needed here, it always equals to…

Refactor: Cycles: adjust microfacet lobe selection pdf by tint

In bsdf_eval() the *pdf is initialized with zero, so it's not necessary to assign zero to *pdf again. I was thinking whether we should remove such assignment in all the bsdf_xxx_eval().…

Cycles: Fix OSL potentially skipping closures when using layering

I don't really understand how it's working. With all these continue, return and do {} while (closure == nullptr) I find the flow quite hard to follow.

Cycles: Rework Principled BSDF Clearcoat

I rewrote EEVEE principled BSDF #111754, and adjusted the part in this pull request so that it uses coat IOR instead of the default 1.5 in the merge commit 445464e5f2999a727d0795b05e0519b73a75b090

Cycles/EEVEE: Change specular tint in Principled BSDF from float to color

Not sure about 7f28729e13, the transition seems smoother without the change. Probably should fix OSL instead.
