Collision problems

[onion pistol]

In tool, when I compiled my structure bsp, I got a whole bunch of these:

###WARNING: a surface clipped to no leaves .

In-game, a lot of surfaces allow projectiles and other things through, but not the player. Like, a wall in my base lets all the bullets and such fly through, but players are unable to walk through.

How can I fix this and make these walls solid?

[Bastinka]

Did you give them the right material name without any symbols such as %, $, etc. at the end of the name?

Or is the model sealed properly?

[Kalub]

Sounds like a linking error too... It's been a while, but check to make sure the player clip walls are linked to your frame.

[onion pistol]

Yeah, the materials are fine, I'll check my linking.

You extruded something from inside your skybox, to outside.

"A Surface Clipped to no leaves" as far as I know means that you have an object (box or whatever) that just levitates, but that could just be me.

You need your bsp to be one mesh that is completely sealed. Don't have models going through the ground or anything like that, unless it's water. They have to be connected.

Render only geometry, who's applied materials have "!" in their names, is an exception to ^wat he said^ and doesn't need to be attached to the bsp, but it's verts and edges need to be inside.

Importing the .wrl would have shown you where the problem was. In case you don't know,
If you use gmax, get the wrl importer from halomaps
3ds users, you're spoiled. You can already import wrl files

Tool creates the wrl files in the CE programs folder.
