Reply To: [Blender 4.5] How do I hotkey/quick favorite the Eyedropper (NOT Color Picker) for use in Texture Paint?
“…so the object eyedropper in the sidebar is not relevant here.”
But it is, because it has the same Shortcut:
Anyway, yes the Sample Color is different than the Eyedropper.
Also, if you have the Mouse pointer over the 3D Viewport and then use SHIFT+X, it Samples the color under the Mouse Pointer.
If you have the Mouse Pointer over the Image Editor and hold SHIFT+X, it only samples colors when you’re over the Image Editor and gives black outside of it.
But Texture Painting is not Blender’s forte….and I haven’t used it a lot, so I am no expert.
Maybe what you want is possible, but I wouldn’t bet on it.
