Composite Material with Vray???

[Dra(hen]

If anyone can help me with this problem I would greatly appreciate it. I am using 3ds max 6.

I created a composite material using Standard materials. The Base material is blue and a red material layer on top of it. I load a black and white image into the opacity slot of the red layer and the result is red stripes on top of a blue material.

Now I have done the same thing except using Vray Materials in the material slots. When I load an alpha channel into the red layer (alpha channel is loaded into the Refraction slot with an IOR of 1.0) it does cut out the red stripes, but its also cuts out the blue underneath it. I get red stripes floating in space.

Does anyone know how to set it up so that the alpha channel does not affect the material layers below?

I don't think it is possible to use the VRay material this way. You could try to use a blend material. Put the red and blue materials in the top two slots, and the alpha in the blendmap slot. Should give you the same results.

I addition to egz's suggestion, I'd also recommend using Blur's MultiBlend plugin, as an alternative to Max's Composite. It allows for multiple layers with masking as well as other controls. You can find it here. http://www.maxplugins.de and do a search for multiblend.
