I’m currently converting a RTCW map over to ET. It uses alot of patches for railings, which worked fine in RTCW, but now in ET they are causing problems. Players get hung up on them, and in some cases the railing is causing kind of invisible walls.
Here’s what’s happening in one part of the map:
The railing curves around down the staircase, but for some reason its creating a weird invisible wall where the red is.
Any suggestions why this is happening?
This is a long-shot, but perhaps a brush cleanup would help. Not sure.
:chef:
If all else fails, write a new shader for your railings with “surfaceparm nonsolid” in it and then create separate clip brushes manually for collision.
I had the same problem… and after playing with it for a bit, i decided to just clip the rails with one brush from the top of the rails to the bottom.
bullets can still hit the rail and get that metallic sound as the clip brush doesnt clip the bullets, just the player. And i can walk around them now without getting hung up where the seperate rail patches meet each other.
Thanks for the suggestion redfella. Found a couple of other problems, but no cigar 
I think I’ll also throw some clip brushes over the minor problems, but still deciding what to do about the invisible walls.
Maybe the nonsolid thing with some clipweap brushes along the rails, or I may just end up making square railings :disgust:
Yes sir 
Have you tried remaking the railings from scratch in a slightly different shape?
I had the same problem with a patch in Railgun (the pipe leading from the depot to a generator by the north crane site). It looked fine, but was creating a collision map stretching upwards from the top of the hill. Remaking the patch with the control points in different places seemed to fix it.
Thanks Wils, I’ll give it a go.
It’s a weird one on all sorts of angles so I was avoiding remaking it, but it sounds like it might do the trick.
Cheers
