Error trying out my map
 

I am making a Luigi's Mansion map, and I keep on encountering a problem when I try to play it. In the map selection screen, I do see my map name. But is says luigimansion.bsp. and other map names don't have the .bsp part at the end of their map name in the map selection screen. and when I try to play it says:

SV_SetBrushModel: NULL

Help!!! Anyways I am a new mapper to tell the truth

A quick google search give this as a result, you could try some of the stuff there.

It's most likely an Origin brush that either isn't attached to anything, or is attached but isn't doing anything. Just remove it.

The name should be the same as in the arena file. Unless you have it set up to read directly from your folders, which would be cool and I'd love to know how to do that.
