That could be enough, in the end we just need some artistic control to give sheen more appearance, if it’s easy to implement maybe you can add it to a 2.3 build, we can test it and if it’s good enough it can stay, if it looks great it could just be removed :)
I implemented the idea. This is with a sheen value of 1.0 (the max allowed before):

Code: Select all

scene.materials.shell.type = disney
scene.materials.shell.basecolor = 0.5 0.0 0.0
scene.materials.shell.roughness = 1.0
scene.materials.shell.sheen = 1.0
scene.materials.shell.sheentint = 0.0

And this with 10.0:

Code: Select all

scene.materials.shell.type = disney
scene.materials.shell.basecolor = 0.5 0.0 0.0
scene.materials.shell.roughness = 1.0
scene.materials.shell.sheen = 10.0
scene.materials.shell.sheentint = 0.0

I think that’s the idea, and I think that should be enough 👍

I’m not sure if 10 has to be the hard limit, but I think that’s the idea and it seems to work, I think it’s the same Lukas did for the Cycles principled shader :)

BTW, 10 was just a test, there is no limit now (i.e. at the limit you will get a totally white material).

Just a quick question before I get my hands on this. It is mappable so I can use texture for the sheen right? I can multiply texture using math node and have strong textured sheen pattern... Right?

Yes, all Disney parameters are textures.

btw legs don't have sheen it's just reflection that makes it look like the outline is glowing :D

By the way, this has to be updated in blender, right now to go beyond 1 for sheen you have to use another node (constant value, math etc...)
Since this doesn't break anything I think it's safe to have it "unlocked" for higher values straight in the disney.

Such a small tweak, and such a great feature for fabrics....
