Working with BSP's

Hi, Ive been messing with the loadbsp function and have a few quetions:

When loading Quake 2 .bsps's most have .tga texures which are not displayed in blitz, is there a way to overcome this? Maybe by converting to .png and re-texturing with Q3radiant?

Is it possible to light map the imported level?

What would be the best way to implement ramps to allow collision for climbing stairs, are there any free editors availible to place objects into the level?

Thanks in advance

Do a search for BSP.

I'm sure there was a demo of little Markio running around a BSP quake-like level, which would answer all your questions.

>> most have .tga texures which are not displayed in blitz <<

Uhm, Blitz can handle TGA nicely. Probably these TGAs are unsupported, are they 8 Bit? You may load them in a graphics app and save them as 24 Bit TGAs.

Thanks for the info guys, I have try a a search John before posting , but didnt find the info that i required. I'll take a more detailed look.

JFK, yes maybe thats it, i'll look into that asap.
