Physics problem with prop.

I'm having a bit of a problem with a certain (prop_dynamic) object. It's one of those spinning vent-tops (I lack a snapshot, but it looks like this), and while it's there, spinning, and I can see it in-game, I can walk through it.

This is probably a simple error, but it's flying over my head right now for one reason or another. What entity do I set it to?

Check what collision type it's using. Some props don't have VPhysics mesh things though, and you'll want to make your own (use a nodraw or blockbullet brush I think would work).

Many props (an unfortunate number of which would otherwise be very useful in gameplay areas) simply lack a VPhysics model, meaning nothing can collide with them, no matter what their solidity settings. You'll usually see an error in the in-game console if you look at it upon first loading the map - often a whole string of such errors - saying something along the lines of "Solid PROP_DYNAMIC with no VPhysics model! [Prop directory here]" That won't be the exact text, but it's something similar.

My improvised solution is a brush or series of simple brushes formed around the object with the "Block bullets" texture (I've used "Clip" in the past, but I think Blockbullets does the same thing in addition to ... well, blocking bullets). For something as small as the rotating chimney I'd probably just use a simple cylindrical brush sized to occupy roughly the same space as it.

blockbullets texture cuts vis, just a notice before you get all surprised over it like everyone else :p

I would use a metal texture, turn it into func_brush, set render to "don't render" and kablam. you have a clip that makes metal sparks fly when shot at.

Let us know, Yes, I've seen those fans before, it's always annoying walking into them in vents and falling through them into the Skybox..
