Composite opacity with shadows
show user profile  Duders
Hi

I'm getting some weird results with composite materials and shadows. have a 100% opacity material underneath a material with varying opacity, but when a shadow is cast on it it seems to hide the opaque material. Rendering in MR with omni lights and ray traced shadows (for now).

Are you trying to do car paint? If so I believe shellac is the way to go, not composite.

I'm doing grime over car paint, for testing at the moment I'm using a Standard as the actual car paint and will use shellac once i have the dirt looking good.

I think a blend mat is the way to go for mud/dirt etc. Could be wrong.

So... Wait a minute. Is that making the material completely vanish anywhere a shadow is cast upon it?

Is one of the materials Matte/Shadow? (Yeah, I know, you've probably checked and/or wouldn't make the mistake to begin with, but it can't hurt to ask.)

thatd be a fun thing to play around with in fun animations and stuff. Cool effect. I wonder if it scales with area lights so the transparency fades.

Cheers Bish, Thats done it. Are composites just a flawed Blend (like Physique is to Skin)?

Thanks to the rest for the help.
