I’ve had this bug before. I used uv textures on some objects and 1 saved the file. Then when I opened the file all textures had turned purple. they are still on the same location in the same map. reloading doesn’t work… Only if I rename the textures and load them again they turn normal again.
of course it is, or at least a way to prevent it.
you see, there’s a thing called “packing a file”
this makes sure that all the images, sounds and scripts that you’ve used wont end up this way that your apparently did.
go to File-external data-pack into .Blend and its done.
The way i see it, this question wasn’t answered at all…so this was a sincere question, not a simple bump! Someone could also have pointed me to “file -> external data -> find missing files”, but i suppose that just is not the way this forum works.
