Yea i make a total idiot of myself by asking this, but is there some weird magic trick to make a custom short lightsaber work? At least it crashes my game when i try to equip it, and i have done the exact same things to it that i do to normal sabers. And they do work. So yeah, are they extracted differently or someething?

Well, it could be attributed to a variety of different things, however you aren't very descriptive. So I'm just going to suggest a little troubleshooting. Download a mod that contains custom short lightsabers, if those work in your game than it is something that you are doing on your own short lightsaber customizations that is causing the problem. If they don't work, you could trying re-installing your game...

If it's crashing with the short lightsabers, I'm guessing that either the model or texture is missing. Follow maverick's advice, and see what happens.

This has happened before with long lightsabers, but it got fixed when i just re extracted the model and tried again. This shortie is not working at all. Maybe it would be easiest to just remake the whole model eh?
