Is there, somewhere a document which proposes a solid workflow across the Substance/Stager ecosystem

Yes and like that!

It would be invaluable for me to have some guidance with respect to a workable Workflow through the 3D applications - can't help thinking that these Apps will be consolidated into ONE sleek, solid package. But, here we are with these largely brilliant seperate concepts with the amalgamated App only a twinkle in our eye.

Can anyone point me to information which will tell me which of the apps can share data - why for example is it not possible to open .obj files in Painter? How then must geometry be prepared to make it Open/Importable?

I have decades of 3D experience but I find myself unable to grok the workflow...

Thanks!
