A Map, And A Problem

Knudsen

<div class="IPBDescription">Stupid VIS :P</div> My map, currently named ns_Valin, is almost 2/3 done (The beta build, that is).

<a href='http://privatesmap.topcities.com/' target='_blank'>http://privatesmap.topcities.com/</a> <- Pics there, feel free to comment.

I recently completed another part of my map, and started the compile. As usual. Only this time I got the wonderful message "warning: Leaf portals saw into leaf". I'd never seen that one before, but Vis was so kind as to show me where the problem was. Or at least i thought so. The coordinates refers to a part of my map that hasn't changed for almost two months now. This freaked me out a bit, but i decided "What the hell, i'll just grap the latest backup and redo the area". Please note that the Backup compiled perfectly a week ago, when i made it, but I decided to compile it again anyway. I made no changes to the backup, but this time Vis decided to tell me that "Leaf portals saw into leaf"
So:
Does "Leaf portals saw into leaf" affect the preformance of my map in any way, or is it safe to ignore it?
and how do i get rid of it? (I hate warnings <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->)

I did do a search, but all i got was "Sorry, but we did not find any matches to display....." <!--emo&:(--><img src='http://www.unknownworlds.com/forums/html/emoticons/sad.gif' border='0' style='vertical-align:middle' alt='sad.gif'><!--endemo-->

I hope i made myself clear, and spelling comes second to ..... anything <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

Hey, I dunno what that error means but I googled on "leaf portals" and found

Hope that helps.

did you try using a -full compile? It usually fixes those. Fast vis gets them alot. That basically means that there is a slop or angle on a brush face that was too harsh or vis just had a hard time making correctly. I know this simply because its impossible to get that error in a flat surface. So check the sloped brush faces. Ive had that error a lot, not really sure how to correct it, even when I found which brush face caused it. I just had to remake the brush.

Hmm, if this is the error that i think it is, it means that a face can see itself. Basically a face of a brush shouldn't at all be able to see another face on the brush, and this is what calls the error. If you look around for any brushes you've manipulated manually (such as by vertext manipulation) and see if that's the case.

I could, however, be hideously wrong.

Leaf portal saw into leaf
There are fine tutorials here : <a href='http://members.lycos.co.uk/EditHalfLife/tutorials/leafs.htm' target='_blank'>http://members.lycos.co.uk/EditHalfLife/tu...rials/leafs.htm</a> and at DeWan's Old Tutorial on BSP and VIS.

Basicly this comes from an area whose floor is not square enough, square floor areas never give this problem. Note: often if there is only one leaf saw leaf in a map level, it can be ignored. So before getting busy, see how your map plays!
Solutions to try when you have a lot of leaf saws, or problems from leaf saws:

1. VIS -full compiles were designed to help with this problem, so the FIRST thing to try is recompile with VIS -full and see if it goes away.
2. func wall any brushes within the coordinates given for the problem, this will simplify VIS in the area because func wall brushes are invisible for VIS.
3. Move walls in the area to make the floors more square.
4. Put a HINT brush across the trouble area. HINT brushes cut VIS leafnodes, so they will reshape the area and may fix the problem.
5. Finally just start ripping brushes out of the area.

Fixing Leaf saw error has also been known to fix other errors in later RAD, like
FindTransferOffsetPatchnum returned -1 looking for patch 1570 in patch 199's transfer lists and other problems.

leaf portal saw into leaf is usually the result of overly complicated geometry in a space. if you have 10 sided pipes that turn at 90 degrees corners or something even more complicated then maybe you should turn them into func_walls.
