What is the Material ID Workflow for Substance Painter ( Blender )

TirvasFreeze · May 2020

Hello,

Im using Blender and im creating right now a 3D Asset it has like 80 Objects the Question is should i join everything together and UV Map it or leave it like that? I saw people joining everything together and UV Mapping it after that and assign a Material ID for each object to use in Substance Painter.. i want to import it in Substance Painter but I'm a bit confused if i should join everything together for the UV Mapping and the Material ID

I hope you could understand me and help me further.

Moved to Substance since this is ultimately about how to work within that.

Oh that's what I meant.

1. you don't have to join them to unwrap together and have one shared UV map

2. you better have same material on them until you want 80 separate materials and separate texture sets in painter

3. simplest way to make ID imo is to bake it in Blender itself

use "object info" node "random" output connect it to "color ramp" node with rainbow style color gradient and then to material emit input. Bake emit with Cycles. Every thing in your scene would get random color
