Vray - VRayBlendMtl or composite or VRayMtl with Composite map


#1

I’m trying to put a decal on a material (a pizza box) that needs to be a seperate UVunwrap (using 3Ds max)

what is the best technique?

using a VRayBlendMtl with the base being the pizza box and the first coat being the logo with a mask for the blend amount, with both channels set to 2 (and then having 2 unwrap modifiers with the box in channel 1 and decal on channel2)

a composite material with the VRayMtl for the pizza box as a base and the Mat.1 a VRayMtl with the decal

a VRayMtl with the Defuse map being a Composite map where the base is the pizza box and the decal is in layer 2 with a uvmap channel of 2 (and its mask)

I seem to have a issue with using the VRayBlendMtl, i cant seem to use seperate UVunwrapping channels for it.
