**System Information** Operating system: Darwin-19.6.0-x86_64-i386-64bit 64 Bits Graphics card: AMD Radeon Pro Vega 64 OpenGL Engine ATI Technologies Inc. 4.1 ATI-3.10.18 **Blender Version** Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: `rB0f45cab862b8` Worked: never **Short description of error** I have a file with about 30 UDIM textures in it. I selected only one of the parts, using 3 UDIMs, copied it and pasted it in a new file. Took forever to turn the texture shading on. I realized that Blender was loading all the textures, even if they are not used. You can see it in the UV editor. This is really inefficient. My 36 gigs of ram are maxed out because of one object. Why load textures that are not even used in the scene at all? We also need a way to turn off BG images in the UV editor. It should be off by default. **Exact steps for others to reproduce the error** - Unzip and open .blend file in attachment Once you relink the files, you will see that both images are loaded in memory even if the UVs are only in tile 1002. That's a major issue. {F9561361}
