Collusions are working right (even if it's tricky to get it to work stable). The problem is, that ellipsoid thing doesn't really fit most cases! It really looks terrible when player can move in a little bit in hole which is a little bit smaller than his bbox! Yeah, you can put invisible block or model there, so player wont be able to move in it, but what if player should be able to crawl under that hole? He'll be still able to walk in it a little bit! Or an other problem that when player stands near the end of the edge and he starts slowly sliding and hanging near the end of the edge, in the position, which should make player fall down already... But well, jcl doesn't care about that... He thinks that all problems could have a workaround... But not all of them should be fixed... That is really sad, at least for me. I'm pretty sure, that there wont be any of those bugs (problems) in grunts with movement, if there were possibility to choose between box and ellipsoid, not for c_move only, but for c_trace as well... Sorry for huge off-topic...
