How to texture specific colors from a bitmap?

[ngel.sp]

Hi, i want to learn how to texture like this:

-There is only one standard material, with a diffuse map

<-- this is the original file

- This material is applied on whole model, but, it's shaded by that specific color pallete from the bitmap

I know this was made with an uvw map modifier, but i can't find how to do it 😞

Any particular reason why you want to use a map created in a seperate application?
You can use a single Arnold material and source material ID's to an array map.

All you need to do is to give the ploygons different Material ID's in the edit poly.
You can even change the colors live linking the 4 colors as actual color feeds not baked, if you want to change them.

This model needs to be included in a software, and it have to be in this way because it can't load a multimaterial 😞

Well then make sure all the bits and bobs that needs to be blue sits in the UNWRAP window where the blue is.

You dont even need to lay it out, just stack them on top of eachother, no need to spend time on arranging them, since its solid colors.
