I am accustomed to have height saved to color image alpha of png files. Comes from photogrammetry editing process that way. The height is never lost . Now I want to make sbsar that would feed that image to Painter with a switch that would treat alpha as regular alpha or sending it to height channel while using rgb as alpha.
How should I name outputs in designer ? Specifically one being regular alpha . Does Painter have some specific rules for alpha naming?
