Marmoset. Problem with material ID map bake.

Stas Mikhailov

Hello everyone. I'm having a problem while baking material ID map in marmoset. I'm importing lowpoly and highpoly models in marmoset and dragging them in the required slots of baker. All the maps are baking fine exept of Material ID map. It goes just blue. I can't understand what is wrong? I assigned different materials to different parts of highpoly model in 3ds max. And when I imported highpoly to marmoset - 3 new materials appeared - so it recognises the material information from 3ds max. Materials have pure colors - 0,0,255 and so on. Does somebody have any ideas? I would be really gratefull.

Hmm yeah that is weird. It looks like you're using the initial 3.00 release, can you update to 3.02 and see if that fixes it? If you haven't gotten an update prompt, you can download the latest from: https://www.marmoset.co/toolbag/

I had the same issue, tried it on 3.02 and the material ID changes colors by itself.

Material IDs are applied automatically in Toolbag, each material assigned to your high poly will receive a unique color that is mathematically calculated to be as different as possible from the other colors. This is a great option if you don't need specific colors, as it saves you the hassle of setting up the high poly materials manually. Also, you can set up base albedo/spec/gloss values with and bake those down in addition to the matID mask.

If you've manually set up colors for your high poly materials with the albedo slot, you can simply bake an albedo map. This is best option if you require specific colors.

A Mat ID is used in various softs for easy selection of groups of faces. It's just an ID, not a diffuse/albedo. So it doesn't matter what color they are as long ast your different parts are properly differentiated : by color ID.
