So this is my first time making a game ready character and I'm already finishing up with the textures. However I think I messed it up. What I did was separate the mesh for different materials sharing 1 UV space. I thought it was a good idea since I don't have to bother with using masks, plus I also see some tutorials…
Ok. I watched the substance painter texturing tutorial again and while they did separate each texture set depending on the material I failed to notice each of them had their own UV space. Guess I messed up.
No worries. I kinda get the idea of what you said. I just placed a fill layer with different color on each texture set and exported just the base color to use as color mask.
to get masks you can use in photoshop... set up a user channel in each texture set put a black fill layer that only writes into the user channel and that covers everything add a white fill layer that only writes into the user channel and and that only covers the geometry add the user channel to your export preset export..…
