Clipping trees (and other FUNC_MODEL stuff)

[Gothi[c]]

I'm making a map with a couple of trees (md2 models imported with FUNC_MODEL). Now offcourse these trees need to be clipped so you can't walk through them.

At first I thought of using regular clip brushes _{(which for some reason don't work for me in GTKRadiant, the brushes show up ingame with the cliptexture saying 'clip' all over it, instead of making them invisible,- yes all faces were textured with the clip texture.)}
but you can shoot through clip brushes.

You can't shoot through trees (or any other solid object for that matter). Is there any sort of flag i can set to the brushes for this? (I'd rather still use the clippingbrush method rather than setting somekind of magical make_the_darn_model_solid flag because i can imagine it would lower the fps because of more complex collision checking.)



_{I DID search the forum (and google) before I posted this, if this was asked before, my apologies, I must have overlooked it, but before flaming me please provide the url to the correct post.}

You could do translucent for the lighting thing, if you don't want a blocky shadow. Where did you find MDL trees?

Brush collision detection is much faster than the per-polygon detection that would be necessary for detecting collision with a model.  I think the best way to do this is to make your collision brushes, and apply the "clip" and "solid" flags to them, then convert them to a func_wall.  The reason the clip brushes showed up with a clip texture is because you need to actually set the clip flag -- not just the clip texture (the texture actually doesn't matter - just the flags).
