[ODE] Another simple BSP colliding question

[Vast]

I know this was asked before, but I have never seen anyone mention BSP Brushes.

They are used for collision in quake (3 and im not sure about others)
so that might be a nice solution for collision detection... ? What
would you say?

On the other hand, there is a tri-collider, where I could build
tri-colliders for visible leafs, and then use that information...
would that make sense? What would be better?

Brushes make a nice candidate, since not all the space needs to be
computed for collision. Yet im not sure since there might be quite a
few brushes...

Please advise on what I should do.. Thanks!
