Title: Sheen Bug
Post by: dj_buckley on 2022-05-03, 15:27:55
Found an issue with sheen.

Let's say I have a 3D Person sat on a sofa, i just want them to cast shadows ready to comp in a 2D Person.

If the sofa fabric has sheen turned on, then the 3D person has to be visible to reflection/refraction otherwise you don't get any shadow from them.

I'm not sure if I understand this.
Your end goal is to have a render of a sofa with a shadow of a person sitting on it, without seeing the actual person, right?

Correct - it's much easier to render shadows and get correct colours/falloffs/angles than it is to fake them in PS, see examples attached.  Files should be named appropriately

In this instance I can get away with leaving the 3D person visible to reflections and just patch the sofa back in, but i'm pretty sure that's not how it should work

Interesting. I guess it means that sheen is a reflection.

We will look into this, but I am afraid this may be expected in Corona.

It's not a huge issue I suppose as I tend to render this as a separate pass anyway when I use this technique.

Be interested to hear what you find
