Merge Substance Painter Texture Sets Into One Image

[@FlowXI]

This video saved me. Thank you

[@unrealhabitat]

I'm very happy this worked for you :)

Okay thanks

hi, is it possible to use this workflow for some mesh that already use opacity ? As for a character with transparent clothes for example ?

[@unrealhabitat]

That's a great question, I haven't tried that yet, but usually for transparency I use a different material, because it will need to be set up differently in Unreal Engine

[@sahinerdem5496]

This method exports outer borders as opacity, sometimes we have inner opacity like fence, Chainmail etc. By this method inner opacities are lost.. Trying to find a solution...

[@unrealhabitat]

Since this method uses opacity it will override the original opacity map of your textures. Im not sure its going to work in that case. I will suggest keeping those materials separate

[@whoisdion_]

Isn't it just easier to export padding as "Dilation+ transparent"...simple..

[@unrealhabitat]

The idea here is to have all different materials merged into a single image, if you are using a mesh with multiple materials there is no need for this workflow :)

[@RowanSkie]

When I try to do this, all I got are transparent textures...

[@unrealhabitat]

Hello, make sure you add opacity channel to all your layers and make sure to add a fill layer on top of all your layers and Alt + click on opacity to make it only opacity, then in the export settings you need to use Dilatation with transparency, pixels 2 or 3. If this is not working it might be something related to UV mapping I guess, make sure to have all your UV shells inside de 0 to 1 space, all laid out out and unfolded without overlapping. If you need additional help you can join my Discord channel and share screenshots, hope this helps :)

Textures come out black from Substance Painter when doing this. Does this happen to anyone else?

[@unrealhabitat]

this might be because you need to add an opacity channel to each layer and export using transparency, also I haven't tested this on the latest version of Substance Painter
