multi materials from maya and vertex colors

bugo

So, while having multi materials in one mesh, the only mesh that receives vertex color while trying to paint is the first one. Is there a way I can paint in UDK on any material of the same mesh?

bugo

no one?

What version, I just did a test in July version on a static mesh with 2 materials and it works for me.

Try viewing RGB in the vertex paint mode, and make sure the color isn't working there, maybe the second material is setup wrong, or is the second material translucent, i know you can't select those in the perspective viewport, maybe you can't paint on them either.

Mind showing an image of what you mean? You're trying to paint two different material on one mesh via Vertex colors OR do you have a mesh with several ID's, and only a couple of them are showing the Vertex Colors?

Also, are you using reflections?

I have 2 different matierals in one mesh exported from Maya. Unfortunately I can't show, work stuff... I am not using UDK, im using Unreal. No reflections.

I'm bumping this, since I got no response. Anyone know what's going on? Why can't I paint in 2 different ID's/elements in Unreal?

Do you have a reflection setup on your materials? IIRC, you could be having this issue: http://www.polycount.com/forum/showthread.php?t=90478

I didn't know you could ever paint materialids with vertex colors.

Texture assignments within the same material is all I know being possible.

Colleague at work helped me out find it, you gotta turn per poly collision ON in all the id's you want to paint in! Finally! Thanks for the help tho guys.
