on the Setup & Painting video at 16:13, you can see the lines/seems of the chest unwrapped on the image. I can not see any lines, I only see the brown color and the grey after I filled the metal brackets. Is there something I should enable? or is this a 2.83 issue
mmoffale When you're in texture paint mode for a selected object, make sure you're using the Image Editor in Paint mode. The setting to enable/disable the UV overlay is "Display Texture Paint UVs":
Keep in mind that this setting should be enabled by default and visible whenever using the Texture Paint UI workspace.
Perhaps it's because none of your selected objects are the active object. The darker orange outline means "selected but not active". Try selecting one of those boards again to make it active (lighter orange outline).
And you're sure that the "Display Texture Paint UVs" is enabled in the View menu?
mmoffale The only other thing I can think to try is resetting Blender to factory settings and try again. If you want to try that, go to File > Defaults > Load Factory Settings. Then open your treasure chest file and see if you UV overlay shows up.
spikeyxxx Do you have any idea what could be happening here?
