For some unknown reason, I can't manipulate my textures while in UV Edit mode (both v2.79 & 2.80.) The texture is applied and displayed on screen, and when I go into UV Edit mode, the UV Map appears over the texture like it should, but then any changes I make to the map have no effect on the applied texture. Resize, rotate, move, the map changes but the texture doesn't and I have no idea why.
I'm trying to edit an old Blender file (probably created using v2.64 but I don't think it matters.) I can't stand the new v2.80 interface (what used to be simple things are now 12-step processes) so I prefer to continue using 2.79.
I'm not a total Blender novice, but I'm definitely on the low end of the scale when it comes to knowing why things do what they do.
Any help is appreciated. TIA.
