This is for my first map so go easy on me =)

1) How do I make vertical sliding doors for ns? The doors I made go sidways then I set them to 90 Degrees (i thought that was up???). If i use the "up" selection for pitch/yaw/roll it just stays there in place not moving. Do they have to have real empty space to move into or can they move through other brushes?

2) What can I do to fix this problem: when i turn on gl_wireframe 2 the entire map looks like it renders from almost everywhere in the map. Even through walls and
doors. How do I prevent this? (I am guessing lots of hint brushes?) Near both spawns ... see the picture below. I added hit brushes but it still seems to render through the brush... Do hint brushes only block in full compile mode?



3) "Warning: Leaf portals saw into"...Can anyone tell me what this means and what i can do to fix it?

Exerpt from the log:

Door problem:
Only thing you have to do is set YAW to up, leave PITCH and ROLL empty. Do this an the door will move up. And they can move trough anything, nothing will stop it from moving (only the settings you set in the properties will )

Map render problem:
Not sure about vis - fast (I never use it ). But anyways try running VIS on normal mode and check again.

Warning: Leaf portals saw into
This is a tricky one, first of all you need to understand what a portal is. This will help you with that:

Warning: Leaf portals saw into can sometimes be fixed with the use of HINT brushes. The problem is that you can see into the room your standing in. The locations given in the error are the Z (side), Y and X (top view) in hammer overview. They can help you to find the location of this error (lots of work).

The cause can also be that you have a room from which you can see into two other rooms with extremely complex entities/brushes. Try deleting these then recompile (after saving in a different file ofcourse ) and check of the number of Warning: Leaf portals saw into are decreased, maybe even gone. I hope that this is the problem since it's easier to fix...

Good luck...

I get these all the time I add a new room, I map very complex (on the very edge of detail the hl-engine can handle). So I know how annoying it is to fix. In the worse cases HINT or deleting a complex brush wasn't enough. I had to rebuild the entire room

I always get leaf saw into leaf. The error is in a room that is not connected to the rest of the map at all (it's in it's own room). But changing stuff elsewhere fixes or unfixes this problem at random (Must be random, because this room is unchanged, miles away from anything) so i just don't worry about it and watch it come as go as it pleases, its kinda funny.
Actually, can someone shed some light on this? Its a room, some pipes(they cause the error) in it. It is not connected to anything, just 1 room. On a totally seperate room, 1000's of units away, i can add or modify stuff, and this will change whether i get the leaf saw into leaf error. I'm 100% sure its this room, because if i delete the rest of the map, or copy/paste that room to a new map, it will error the same (same co-ords, etc)
