Drastic Memory Overflow: Fell out of small block heap

Nac_zr · 08-18-2012, 04:28 AM

Im new to using Hammer and I have been messing around trying to use it to build maps for Portal 2.

I have been building the main puzzles in the PETI editor and then exporting so that I can use Hammer to polish them up.

Recently, I have been getting this pop up in the map compile output.

Drastic Memory Overflow: Fell out of small block heap

It carries on and completes but when I load the map to test in the game, the player start point isn't in the lift and I am stuck in the corner of the first room and have to noclip to get free.

This started happening after I constructed a model of a railway line. Is the model too complex and eating all the memory?

Any help or advice is welcome, thanks.

Im assuming you googled the error term and the first three hits didn't contain usefull hints?

I found this "You have too much, too small brushes tied to func_detail. Remove as much of them as you can and then try a compile again. If it still doesn't help, select them and press ctrl+shift+w to make them world geometry again."

Not having the greatest understanding of Hammer (this will be my 3rd week of using it ) I can only think that this means that the small items that form part of my rail model are too small and/or there are too many off them. I didn't know that hammer couldn't cope with that sort of thing. I will try deleting them.
