I know there is output node I can set randomly to any node. But it's mostly unusable if output require other format. I open some pixel processor and couldn't understand a thing usually. It's very SD thing actually.
Super cyiptic and undeciferable.
Let's see at Blender for example . It's shader editor made me learn about CG a lot just by ability to show real time output for evry math opration ( with help of some normalization on and off) . It's very visually illustrative. It's geometry nodes "viewer" node shows your a lot what's actually happening in each stage of node flow, up to exact digits.
In SD it's a crypto puzzle you have to figureout yourself . Please do something with it.
