The Atlases Again

I removed all worlds, UIs, removed all unused components images, objects, sound etc... I mean everything

and left with start UI and no objects or actions nothing, but still atlases are not empty!!


Is there a manual way to clear atlases?

 

Hello, close the BB and open BB.
In Menu Tools, Remove Unused....

Then view Atlasses, Optimize an Rebuild.

 

Yes , bbdoc rename in rar . Than Go to WinRAR Files Go to the Image and delete unused graphic . Than rename it in bbdoc and rebuild atlases .

 

Yes this is the only way I could manage to rebuild the atlases without any extra unused images

 

Can someone please describe how to do this in more detail? I'm having trouble. I've definitely tried what @jcalle suggested.
