Confused

ok i have a map which crashes hl everytime i run it.

then i optimize
(see pic)
no errors and hl crashes same place every time.
WILL those 3 warnings crash hl?

the third leaf portal has a large z distance.
so your hall of mirrors is HIGHer as an onos (230 - 460) !

the (x,y,z) coordinates are the corners of a face between 2 leafes.

go to (-1200 , -2800 , -300) (=lower left) and decrease the level detail there, transform stuff into brush-entities, make less curved surfaces, make surfaces of 2 objects beeing in the same "plane".
If you dont want to change the architecture you can use clip brushes wisely to tell the compiler how to make leafes correctly... (this might invrease VIS and RAD time much!)

Spider

Also, another cause of the "Leaf portals saw into leaf" error is if you have applied the 'clip' texture to any entities. I encounterd this problem early on in my mapping and it was relatively simple to fix. Just think of any clip brushes you have added recently and check them all out to see if they are entities. If they are then simply change them back to normal brushes. But it may just be that your brushwork is too complex in some places and need to be toned down.

Confused

yeah but will it cause hl to crash?

Ollj

If you see no other error messages fix the known errors first ... vodoo comes later.
what did u change since the last working version?
EVERY ns specific entity can cause werid crashes.

confused! -

"portal saw into leaf" will ALWAYS cause HL to crash ... what this means, in essence, is that you've created something that is physically impossible for the engine to render, either by vertix manipulation, clipping, etc.

the easiest fix is just to save the map, then start deleting brushes around the area of the errors (using the x,y,z coords listed) ... once you pin-point the problem-brush you can reload your original just just delete those.

deleting the brushes that are causing this is usually the easiest fix ... then just redo those brushes,

I have always 3-5 "leaf portals saw into leaf" and the map runs fine...
Can even watch them ingame without big problems.

<span style='color:white'>Be nice. There are numerous tutorials out there which state just what he said.</span>

Confused

well i think my rmf is simply ****ed up
i cut everything except the ready room and it still crashed
unless i have an old version of xp cageys tools.

so im gonna put it in a new file
and re dpownload tools

i finally found teh error log <img src="style_emoticons/<#EMO_DIR#>/smile-fix.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile-fix.gif" />

"Leafs" are the convex spaces that hlvis divides your map into. The boundaries of these spaces are either opaque faces or "portals" which connect to other leafs. "Leaf portal saw into leaf" means that one of the portals of a leaf saw into it's own leaf which is impossible if the leaf is a convex space. It is possible to decompose any hull into convex pieces but evidently, hlbsp doesn't handle all cases which is why you get these errors. I'm curious which specific cases these are.

not quite right - i think you are confusing concave bad brushes with leafsaw errors. true, sometimes leafsaws are from concavitys and cause crashes; but also sometimes they are just floating point errors and will cause only minor lag additions within that leaf.

so you don't HAVE to go postal at a leaf saw, but feel free to if you want to! <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

IT's a hard error to get by.
I usually redo the whole area where it gave me the error, little by little and compiling each time.

Confused

I FIXED IT!@!@!

i have been wasting my godamn life trying to solve the problem for 3 days then i decided to plaay and ran hera and the same thing happened reintalled hl = ns and it works happ happy joy joy
