I'm working on a map and hit a Leak. I used big block technique to find it and, er, I don't understand what I've found.

Basically, I've now got a 2" cube floating inside my level. With it the map compiles fine. Without it I get a leak. The cube is inside the level, and is in mid air (i.e. it doesn't intercept or touch any brushes or faces). I've scanned the various FAQs and can't find any explaination. I wasn't working anywhere near the vicinity when the leak occured. It's nowhere near being the origin of any rotating entities (and anyway, as I said, it's inside). 

Grateful for any suggestions as to the cause.

Thanks,

only a few times have i had solids puncture my map and create a hole..

i had one of those "to infinity" invalids.. when i deleted it.. it made this oddly shaped hole in my outside walls, where both ends had passed thru into the void..

doubt its the same here, but still.. i felt it noteworthy..

you guys should make these posts as suggestions..

even if its wrong, i am betting it will go into the search as options in the future..

besides, its a valid comment.. it could be the correct answer..

send them to me..

drs_orpheus@msn.com

zip them please..

request a pit from lep, so you can post images more easily in the future..

i will post the pics for you, no promises that it will solve this , but it could..

post any error messages associated with the compile as well..

It was running in sw mode that fixed it. Thanks. Makes you think you're playing Doom again mind.

A couple of thoughts on the shrinking block technique.

1. As per this particular threads example, the particular area of space isolated may not be the point of the leak at all, even if blocking the space fixes the leak!

2. As I understand it (and as experimentation appears to confirm), the block need not be over the leak to stop it, it merely needs to block access to the leak for all entities. This means that it can simply be across one or more routes (corridors) that allow the player (or entities) to reach the point of the leak. This means that, as you shrink the block, you need to be aware of which routes become open, rather than just the physical location of the blocks.

3. From #2. a technique based on bloody great bulkheads specificaly designed to block corridors seems to work, with each bulkhead designed to block a single corridor/route. Once the leak is isolated in a single area you can then use the block technique.

Of course, all this is based on extremely limited experience (albeit with a fair level of experimation), so might be b****cks. I have to say the pointfile trace in HL seems much easier though.

Grateful for more experienced views.
