Is there a way to extract BSPs so that they can be imported into 3DS Max? I'm making an on-rails shooter for a college project, and my modelling skills aren't too great, so I've been using the models from Halo 2. I know the BSPs can be extracted, but can they be imported into 3DS Max?

Thanks

yep open entity and extract the bsp and save it then open one of the many .obj's in 3ds
