.Map :: MoHAA Mapping

I'm having this error while I try to load my map. Please HELP!!

FS_ReadFile with empty name

Any idea?

If you added an ammobox_mg, remove it.

Thats the most common reason for this error,but there can be also other models.
Remove all sparehead models and this error is gone!
Beliefe me i had the same error with the ammobox but also a few other things like a book or whiskeyglas.

Yeah, it was the ammo box. Thanks a lot guys!

Just for the records: I had the problem before, in a early stage of my map, and the only thing I had done was a boulder. I was messing around with the shape of an sphere and I made this rock. When I went testing, I got the "FS_ReadFile with empty name" error. So the "boulder" was the cause. I opened Radiant again and realize that the new brush didn't had a name (noob way of think...). My solution: I select the boulder, right-click on it and "Add to Entity" (I think I was "adding" the boulder to a valid entity "list"). For my surprise, it worked. No more FS_ReadFile error (there was no ammo box at that point in my map). So yeah, other models can make this error happen.

By the way: So how can we put ammo on our maps?
