Help. Problem with vray blend material.

[Shogoki2015]

Hello folks,

 

a simple problem, but i don't seem to get it. help would be much appreciated.

 

i have a basic concrete wall and i want to apply 2 blended maps to it by using a vray blend material.

 

one is a leaking map to add some age to the wall, the other map adds some more imperfections. for simplicity i'll just name them coat materials A and B.

coat material A is set to map channel 2. coat material B is set to map channel 3.

 

base materials for A and B are both darker versions of my concrete material.

coat material for A is a leaking jpg (b/w), for B it's a dirt jpg (b/w).

 

i can edit them both in the uv mapping modifier by selecting the corresponding map channel and enabling "show material in viewport" in the material editor.

 

the problem is: whenever i set the uv mapping channel to 2 or 3, only that material will show up in the render, never both at a time. if i select neither 2 nor 3, none will show up.

 

i hope that descriptions works without pictures

 

is there a way to get both (or more) channels to show up at the same time?

 

thanks and ... cheers

Just add two uv maps... one in channel 2 and the other in channel 3.

that did indeed work ... not very intuitive imo, but ok.

 

thanks daniel, cheers to you.
