Maya to SD with ID color

[Jeronimo358652756mc1]

Good morning

I have an object with different types of materials. I assigned a different color to each part of this same object - which has UV - so that each of these parts would have a different material.

When I 'link' in Substance Designer, how can I make each part of this same object have a different material (or a different tree and still view it as a whole in the 3D viewport)?

I would like a tutorial on this, I can't find much on the internet.

Correct me if I'm wrong

1- My object was exported from Maya without any UDIM, just in a single layout and all the pieces in that layout;

2- I linked it to the SD and assigned a different color to each material I used as an 'ID';

So, can I work with different 'trees', different outputs and values ​​for each UV piece of a single object, in other words, each one with its own color, hbo, height, normal, etc. and, therefore, make each material unique (of course, depending on what you want with it), right?

On the other hand, what confuses me is that I could use a single tree, but I don't know how to 'separate' the faces that I assigned a material to in Maya, making them unique (with different outputs for normal, height, hbo, etc.).

I don't know if I explained it correctly.

Hello @Jeronimo358652756mc1,

If your 3D scene has multiple materials set on a single model, then you may indeed assign a different Substance graph to each material.

It is best to keep graphs separated per material to minimize the recomputations required as you iterate on each material. It also makes your materials more flexible and reusable across projects.

Best regards.
