SBSAR in Photoshop?

gnoop

 I am trying to do a sort of grand comeback to Photoshop.  Blowing dust off my sub I am still  paying because of old habit.    Chat GPT script writing + Photoshop event listener made it super capable again.   Chat made me super helpful one click  "crop from master file and export material channels  from layercomps "   script  working around  old  SPainter limitations and saving me from the  hassle of Designers  Gordian knots and missed resources  nightmare.  My own files took me an hour sometimes to figure out how the hell I made it work last year.    Also Photoshop is still a champion  to clean/work with photogrammetry materials. 

 So I entertain an idea of  using Photoshop again as a workflow speedup.

They added sbsar support  for smart objects that could work potentially as live filters working in 32 bit float math internally for 16 bit integer document.   

    So far I figured the document should be power of 2   size . Otherwise sbasar resale it internally . It works a bit slower than In Designer  still  could be quite helpful.      

   

 A gray looking  RGB smart object   works as grayscale input just fine.   Height to normal map node works. 

Some of my pixel processors also work fine , like old frequency separation tricks.     But sometimes I get just nothing.     Couldn't find any info , any example sbs or any specific Photoshop template  for Designer.  

   Anyone   tried it and have some ideas to share?
