flat projection

[klex167]

Hi,
I have some trouble with the flat projection. In the example below I try to put 2 "stickers" to a cube with flat projection. If the 2 materials are different (like "1" and "2") its working. BUT when the 2 materials are the same (like "1" and "1") the first material will not calculated.
After some investigation and finding the problem my workaround now is to duplicate the material. But that is not convenient.
Do you know this issue?

Best klex.

It has always been like that, since the old VrayforC4D version. The workaround you have used is the way to go, and yes it would be nice to avoid duplicate materials.
For decals you can also add a second surface slightly offset from the main object and add the maps on that, this give more flexibility despite non being the fastest solution.

I had the same idea with the second surface right in front of the basic surface. But if you use VrayDirt in the first surface you get a dark area where the additional surface is. Even where you have a transparency.
Do you understand my complicate words?

Do like this, then it will work

This is without the decal exclusion:
