Sometimes, when you "enter" inside a model, the game crashes and gives a fatal segmentation 11.
I don't know what causes it, but it seems the higher the vert count, the higher chances of it happening.
It's quite inconsistent, so i won't drop a zip file with a example model here, but i think it's something to look into.
Tested it on Iron Fist, which is forked off RE 1.2, and it crashes there too.
Maybe it has something to do with collisions?
