Is there any way of deleting unnecessary datablocks? they are a pain in the *ss, they use a lot of memory if you have created lots of object, and then deleted them. HELP!!! :-?
Click the little X in the top left hand corner.
That doesn’t delete them, it just deletes the objects link to them. Try compressing the blend file using the File>Save Settings>Compress File option (you’ll need the publisher key). I’m not sure if this will delete them or not but it would make sense if it did.
