Optimize scene size does destroy guides

Is this a known issue? Optimize scene size does delete somehting in the guides.
I cant build anymore.

This is not really a “bug”. You are running a Maya command that automatically deletes a whole bunch of nodes. You have to be extremely careful when you run that command. Especially the “empty groups” option, which will delete useful transforms that are used for holding attributes or metadata. “Unused nodes” can sometimes delete utility nodes, even if they are connected to things.

If you are having file size issues, a better option is to select your guide and “export selection”, or specifically find the nodes that are causing the problem, and delete them yourself. Don’t trust Maya too far!


Thanks thats great info!
