Hollowed polygons wall visibility problem O.o(Solved)

[Ajw1]

Tried to make a pit in game, so made pretty big polygon, with 20 sides, and it looks allright in radiant..but when i made it bsp via q3map2 build in game it just dont show part of walls...you can see whole map from the underground :/ how can i make every wall visible? at least from the inside...help please

the brushes are conflicting (touching inside of each other). try moving them around so they're at seams with each other, not touching.

are the walls textured? or just caulked?

uh they were textured but nvm, ghost helped me. they were jsut too thick after hollowing, i made it manualy and now everything works fine
