Brush into .obj file?

[Mystic Monkey]

So I'm experimenting with this map that requires a huge cylindrical room. Like, 32-walls huge... all those walls I'll have to allign correctly, can't be good for the map's brush-limit which I'm already concern I'm pushing and I really can't be bothered assembling piece-by-piece. (The map I'm working on is rather "complex" given what it's based on.)

But I know some maps use props not just for skybox decoration but for large terrain structures that would be too complex for brush-work. I was wondering if it was possible for me to place a large cyllinder in my map of the chamber I want and somehow import that brush as an object file? That way it will retain it's size while I can work on it. When it's done it will count as the one prop instead of many brushes and with Vphysics it would be hollow in the middle to be used as a chamber.

The only alternative I know of that could work is to make a 8-walled arch-circle, displace the out and inner walls and subdivide. This appears efficient but it will be difficult adding entrance and exit doorways.

You should check out Propper, a program that converts brushes into models.

Here is a guide by DrSquishy: https://tf2maps.net/threads/guide-getting-propper-working-nowdays.38589/

Thanks, I'll mess around with it. It be nice to have some advance-shaped rooms in my maps.

With it I figured out how to export brush made structures into .mdl files. I've yet to figure out how to turn them into .obj but I think I can do so through Blender.
Just wanted to say thanks again.

Try the -obj command line flag in Propper. https://developer.valvesoftware.com/wiki/Propper#Compiling

Thanks, though I don't think it's working right.

Because you put the -obj parameter between -game and its value. Put -obj before -game.
