Wall textures visible through floor

This issue should only present itself with middle textures two-sided lines. If they are two-sided, delete the sectors that are supposed to be walls.

If this situation comes up later and you DO want a middle texture on a two-sided line(like when making bars and grates), all you need is a difference of sector properties between both sides of the line(which can be as little as a 1 point difference in brightness!)

From the look of it, I have two guesses. Most likely you forgot to add lower texture to the bottom of the door, which has elevated floor. Less likely is you used middle texture on a non-solid wall and those don't tile unless they are on solid one

The middle textures weren't double-sided, but I changed the brightness of the sectors and that fixed it! Thanks!
