I'm having the same issue. I tried baking from my finished base geo back, force use bake, no luck. Tried ignore baked cache, nope. I tried exporting, importing graph into a new file. Build "range" setting tried Remapped, Proportional, Normalized, Raw all the same. like the below. I was hoping to use this on a project coming up but might have to abandon. Also is there any way to export a standard texture set or is it just basically all custom AOVs.
export
build
