So when we export a material as a psd we could have it with layercoms like : base color , nomrall, spec , mask 1, mask2 etc. That way we could just drop that exported psd as a linked smart object to Photoshop master document and switch layersomps having a single material layer the same way Substance Painter represents layers .
I just want to try material mixing in Photoshop. Being per pixel accurate without sub-pixel blurring like Painter or Sampler , never asking for missing resources and having quite nice brush toolset it needs just a few extra help on SD side to be quite a nice texture compositor. With chatGPT finally writing working scripts for Photoshop I am doing a big comeback currently.
