Transparent Texture Problem

In my Doom 2 WAD, I made a transparent fence texture. But, for some reason, the texture stretches below the floor and you can see it. Here's an Imgur link of the problem:

This is a common software rendering glitch. You have 2 options how to fix it:
1. Make it so the 2 sectors on opposite sides of the glitched linedef would have different Brightness values, with difference at least 1 unit.
2. Make it so the 2 sectors on opposite sides of the glitched linedef would have different Floor Height values (if the texture bleeded through floor) and/or Ceiling Height valies (if the texture bleeded through ceiling), with difference at least 1 unit.

Scifista's already posted the answer, so I'm just going to say that this fence looks badly overscaled. It'd work better if the meshes were much smaller.

Thanks. I'll see if that works.

It works! Thank you!
