For a map I'm making I want to use a metal grate brush(texture: underground_metalgrate001a ) that blocks players and physics objects, but lets funnels(AKA tractor beam) through. I already tried a couple of things:
- Overlapping with a clip / playerclip brush, they block the player but let physics objects(eg cubes) through
- Overlapping with a toolsinvisble which also blocks the funnel
- Tieing the grate brush to a func_brush, setting "solidty" to "always solid" and adding the funnel entity in "NPC class excluded from collisions", but it still blocks the funnel

So, can anyone tell me if there's a way to make a brush(or set of brushes) that A. blocks players and physics objects and B. lets funnels through

Thanks in advance!

Try a block bullets texture and set your grate solidity to not solid

Not working, it has the same effect as clip/playerclip textures for me.

How about 2 player clips 1 normal nothing special.
The other, tie it to a func_clip_vphysics

Thanks for the quick response, this works exactly as wanted.

EDIT: sorry, I was being a bit sleepy with testing this, it still blocks the funnel. So I'm still looking for a solution.

Bumping this thread because I previously said it was solved, but didn't test properly.

Did the func_brush have solidity to never solid and No collisions?

I ran into a similar situation
got around the problem using a func_clip_vphysics stacked on a playerclip brush, stacked on a func_illisionary for the actual appearance.

So, three brushes, one blocks players, one blocks physics objects, and one has the texture on it and isn't solid.

Make sense?

Ah, I overlooked this, I closed hammer before saving it with the func_brush. It works fine now.

Thanks again and excuse me for being so chaotic

Put another brush in the same place with a trigger texture tied to func_clip_vphysics to block physics objects. This does seem quite a workaroundish solution though.

Well, it isn't really a brush, but you could use a light bridge, and put a fizzler behind it. The lightbridge can block the player, but will let the tractor through, the fizzler can block portals, but the lightbridge can ensure the players and objects won't be pushed into it when in the beam.

This way, at least, you wouldn't have to bother explaining to the player the new functionality of a wall solid to everything but funnels.
