Brush out the railing and texture it to your pleasing with a texture that begins with a '{', Example = {catrail-a
Then click the brush, select EDIT then PROPERTIES (Or ALT+ENTER).
Choose these options:
CLASS: FUNC_ILLUSIONARY
RENDERMODE : SOLID
FXAMOUNT: 255
Now make a brush the exact same dimensions as the railing you have just created but this time change the texture to 'clip', then put this in the exact same place as the railing brush.
EXTRA NOTES :
1) The above was an example, it allows marines to shoot through the railings.
2) Adding the 'to world' tag onto a noclip may or may not saver r_speeds. Someone told me it does, someone told me it doesn't.

x would equal the spacings..
and I have to make a separate brush for each line?
Fill an area that would be used for ambience, for example an area outside a window onlooking an inaccessible room, with a solid clipbrush. Clipnodes are your enemy. Keep them as small as possible. I would then tell you to crush them, but since clipnodes are also your friend...

Nah!
The whole set of railings is made from one brush the blue bits in { textures are transparent when those textures are used on entities with rendermode solid.
A better example might be...
I have a wall, it is covered with lots of small brushes to resemble complex pipework. The gaps in the pipe work are physically too small for a player to fit in, but players could get caught up on them as they walk past. The areas between the pipe details are automaticaly filled with 'clipnodes', these allow players to (poytentialy) enter that space. Brushes covered in the CLIP texture are completely invisible but block player movement. By enclosing all my pipe details in a brush textured with CLIP I can prevent the compiler from creating all the little clipnodes between my pipe detail brushes. This means players won't get caught up on the pipe details anymore and reduces the load on HL.
The reason you might want to use this technique with a railing is that if you use func_wall you will have gaps you can see through but not shoot through. When you try to shoot through the gaps your bullets hit the func_wall instead of going through the gaps. By using func_illusionary (which is not solid in-game) and a clip brush (which you can't walk through) You get a railing with gaps you can see through, shoot through but cannot walk through.
btw here's an offtopic question:
does ns support trigger_gravity? didn't seem to work, maybe i did something wrong <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' valign='absmiddle' alt='smile.gif'><!--endemo-->
and is trigger_push possible to make go up?
i'm quite sure i made the right configuration but doens't seem to work.
Also, I have a question! Yes, I do!
Instead of clip brushes, do func_wall entities get rid of excess clipnodes?
That way skulks can climb up the area. Why can't it be made so that skulks can climb CLIPs? It might be a good idea.
Its sometimes annoying having to make so many entities in an NS map... especially with the entity limit, and the fact that entities cause increasing lag when the map is being played.
I would guess that func_walls don't get rid of the execess clipnodes, because they are entities can be changed (read moved) and if they are moved the space they were in would need to be passble (part of a clipnode).
I guess that skulks wall climbing is based on wpolys that make up the walls rather than the clipnodes. CLIP brushes don't have any wpolys (all faces removed during compilation) so skulks can't climb them.
I'm making a lot of educated <i>guesses</i> in some very technical terratory here, but if anybody <i>knows</i> better i'd be glad to learn. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' valign='absmiddle' alt='smile.gif'><!--endemo-->
I was wondering that.
Just couldn't get it work right.
Actually Merkaba used a trigger_push to get the low gravity in the easter egg room, you can tell this because when you jump up it's all jerky.
I think the trigger_gravity is borked currently. I seem to recall it being borked in the pre realease mapping builds of ns (which would explain why Merkaba used a trigger_push instead of a trigger_graity in the easter egg room)
