Is it possible to lay out materials based on mesh mat ids?

Can anyone help? I am wanting to import a mesh into SD and map existing materials to it based on the material IDs of the mesh.  So that I have one single output with all the materials laid out like an old school flat texture for a prop? I currently have no access to Substance Painter.

bake color to texture from material colors and use it as an ID map for a material blend node.

Is this possible if it's just a low poly object? or does it need HP and LP?

You can tell it to use your low poly as a high poly
