Hi, I am playing around with the Ogre demo app "Bsp Collision". It has a .bps file. I want to edit this file. So what I found out is that this is some quake format, so I downloaded GtkRadiant. This doesn't open BSP files, it only compiles to BSP files. So then, I found a BSP-to-map converter called winbspc. I tried to convert the file with this and I get an error saying that it is an unknown BSP version. Has anyone tried to do this before? I'd like to have some kind of starting point where I can test things, that's why I'm trying to use this BSP file from the sample. Does anyone have any other suggestions here? Thanks, -- Rocky
