Substance designer and ID

'Do I need to make a colored map to make the 2-material blender' You would need to make a map to use the material IDs.

'what is the best way to export to blender through the substance designer integration addon? is it by publish?'

The Blender add on uses sbsar materials (i.e published materials).

You may want to consider an alternative workflow between Substance and Blender, which will use the strengths of Blender, Painter and Designer:

1. Model in Blender.

2. Unwrap in Blender and assign materials

3. Export from Blender in FBX format

4. Make any materials that you need designing from scratch and publish to Painter's shelf.

5. Import your fbx to Painter and bake

6. Apply and paint your materials, both those designed in 3 and those in your libraries to each texture set. That way you can build up the materials in layers adding dirt etc as required

7. Export texture sets from Painter

8. Back in Blender use Node Wrangler to connect those exported texture sets to the PBR shader with one click for each set.
