I know Adobe offers Substance Sampler but It's so inconvenient in its evry aspect . Why not just let us construct our own filters for Photoshop in Substance Designer ? Or use sbsar as smart objects sampling beneath layers ot better layers of choise .
It would solve the main Photoshop issue, an ancient layers only design and lack of flexibility . SBSR files as smart object would turn Photoshop in supeper advanced image editor not only for textures.
I see so many options. dynamicly updating masks , depth aware CG images compositing, whatever filter forge is offering etc.
