I'm interested in using Substancer Painter, but as well as texturing models I would like to make some generic textures that I can use in other applications as to textures models or use the maps for shader creation. So for example if I wanted to make say a wood texture that I could apply to any furniture model I have in other apps (e.g. daz studio, blender, poser)
But I'm wondering how to start doing this in SP as normally you import a model to work on. So using the same wood example I wouldn't have a model to bring in to create the wood on. Should I do something like just import a sphere or plane, some other primitive object and use that? Or would that cause problems with the maps because of the sphere's UVs? In something like Daz Studio I would be using the model's default UVs and then plug in the textures where I need them (colour, roughness etc.).
I'm new at SP (trying out the trial at the moment) and I haven't used a 3D paint app before, so any advice would be appreciated.
