How to completly block line of sight with destructibles?

[Synad]

Hey there. So I'm using these sweet wall models to make a dungeon in my map. The problem is, I cant seem to figure out how to make the walls completly block line of sight. I tried Line of Sight Blockers and changing the walls to have Fat Line of Sight, but units can still see things beyond the walls.

Any suggestions?

Silly me, there was a special solid black tile in one of the packs of the modeler. Problem solved!

by solid block tile, do you mean the black empty wall doodad? Or do you really mean a tile on the ground as in terrain tiles?
