How to find image usage? Outliner / Data API / Images I try to shrink downloaded FBX files, sometime I succeeded, sometimes not. I try to find out what image I could not unpacked. Now I realize there are images what are packed in there (bleder file) but I could not see in the material properties. Where are they, how I unpack them?
These are possibly two different questions :).


To unpack an image, go to Image Editor and click the Unpack icon.
To remove unused images, select all and RMB > Clear Fake User.
All unused images will be removed after reopening your .blend file.
Only images that are currently in use will stay in the .blend file.
