Hi Karen,
I just tried to recreate your set up. I have two windows open. One is the 3D View set to Edit Mode with the “Show Overlays” button turned off (this helps me see just the texture without the wireframe) with the “View Port Shading” set to Rendered. The other window is the Image Editor set to Paint mode. I created and saved a new texture file and plugged it to the Base Color of a new material for the object. With this setup I can paint directly on the UV’s in the Image Editor and see the paint strokes show up on the object in the 3D View.
I hope this mitigates and meliorates the morass of our memory until the materialization of the mysterious methods of our modeling mentor….. I’m not sure where that came from.
