Static Mesh + Karma vs Builder Brush

Hi all, I was wondering about something. I'm working on a level, which only has floating platforms. Since I'm somewhat skilled in 3dsmax, I made the models in there - and imported them as static meshes. All is still well.
Here's the thing. Once you're killed, you fall right through it. I don't fully understand yet why, but I think it has something to do with karma stuff.
So what should I do to fix this? Import the model as brush and add it as a regular brush, or try and fix it with a good karma model?
Cheers!

ps: here's a quick screenshot from the editor to show what the current scene is:

What you want is a simplified collision model for your static mesh. I don't really remember how to set these up in 3DSMax, the last time I tried creating these was with Maya and it involved creating a low-poly version of the mesh and grouping it with the normal-poly version of the static mesh.
You may want to look at

Oh this bug puzzled me for the longest time in my earlier days.
I'm assuming you've myleveled these static meshes.
Once you've done this, there should be some additional properties at the bottom in the static mesh browser.
Materials (this is what kind of textures for your model)
SimplifiedCollision
UseSimpleKarmaCollision (If you don't have a collision model, set this to false and your problem is solved :)
But if you have a collision model, you should set that model one to false instead for faster performance.

Wail, I actually did look at that page, however it said that the karma shape should be convex - which simply isn't possible in this case: the static mesh has a lot of bumps and dents in it. But thanks!
Ant: thanks so much, that did fix it! Turned out I couldn't even add it as an additive brush since that would freeze up the editor... guess it can't handle 18K meshes that well ;)
