Ever since my map reached beta status, the Alloc Block full error and me have been meeting a lot... I think that is because I didn't yet figure out how to make the info_locations correctly. My map compiles without errors and warnings, but crashes on load with the alloc block error.
However if i compile the map without the info_locations, it's doing just fine.

A thing i noticed is that when i delete the info_locations, clipnodes are down to 90% and leaves to 87%. Someone said the alloc block error starts occuring when clipnodes are going near 95% so that might be a cause for the error too.

I placed my info_locations about 512 units below the rest of the map, all 16 units high and null textured. Every info_location consists of only one block and there are no intersections. Is there anything I'm doing wrong or do I have to start reducing clipnodes (I already did that, so it's not really an option... I would have to rebuild/delete stuff)

Hope someone can help me on this, or share their experience with alloc block errors...

For what it's worth I put them 512 grids underneath the map and they are all 1 grid high. Perhaps have a look at using even more clipbrushing on stuff you don't want to have cliphulls, I did that to on each and every insignificant looking detail on walls for example. Think in terms of pillars, wall details like computerscreens, tiny protruding things and just encase them in a flat wall/ceiling/floor clipbrush? Just keep an eye out for the floating in mid air thing...

Hope you'll get it sorted out...

Are you using the latest version of the compile tools? It wasn't until I think about p15 that the bsp optimizer was built in. Good luck.

I just did a compile with -noclip and the error is still there.. so it can't be a clipnode issue..
Oh and yes I am using ZHLT 3.4 from amckern, it's just that ns_disonberg is huge and very complex

You could fiddle around with the location of the info_locations. I haven't tested it, but do they clip the player when put in the areas where the player can walk?

Or maybe just putting it closer to the bottom of the map or perhaps even above the map could work. I dunno, just thinking out loud here...

They dont clip players, in previous (working) betas i had the info_locations as big as the rooms itself and i didnt get an error. I've done about 50 compiles or so since last weekend and i cant figure it out There is also no detailed explaination of the alloc block error on the net... im really desperate
