Our tech artist also uses Substance Designer for exporting textures or uses the node graph that's available in Substance Designer to script and essentially use it as like a pipeline tool.

I've seen some things that he's made where he would use it to, if he's got a bunch of textures that he wants to include in one,

texture, he could use it to lay out the textures neatly so they don't overlap or anything like that.

And he doesn't have to do it manually himself just to speed up the process.
