Quick question regarding modifying original 2001 tracks

Hi all!

I'd like to add 3D objects (like choppers, trucks, buildings) to original tracks (2001 tracks).
If I edit the original tracks' wads using GP4 Builder, will that cause problems with the game? I read somewhere that original track wads should not be modified...?

Thanks guys!

Ps. I use CSM.

It should work. I can't see any reason why these tracks could not be edited. take care at Imola thought...
Also take care at the vertice numbers. Maximum is 300 000 for a track. adding new stuffs, If you are over this limit, the game will crash.

but to be honest, I find a bit strange to want to edit these tracks which are very low resolutions in term of textures...
when I start the original game with the original tracks, it looks so poor....

Ok thanks, I'll give it a shot.

Haha yeah I know what you mean, but I find there's something charming from the original tracks.
