Selection of Models

How do you change where you can select a model ingame? Preferably a way to do it in Magos'.

If you can't select a model by just clicking on it (meaning you have to drag over it to select it), load your model in magos, go to edit, calculate extends.
take a back-up though .. I'm not entirely sure if this work.

Then whats wrong with this?

Try this. Use collision shapes next time :P

Yea particles can't be selected by clicking them :P
