Resources Manager
Resources Manager addon helps you organize texture maps, videos and linked libraries in your blender file. It does this by keeping track of every material and object referencing that resource.
-
You can instantly see if a texture is being used and where there's any material or object referencing it.
-
Consolidating will pull them from the various locations to a folder relative to the blender file you're working with.
-
Rename resources simply by double clicking.
When you're certain you don't need a specific resource anymore, you can delete them to keep your blender file.
