Transparent textures not working

This is the problem:

I made my own texture (in the map.wad file). The texture has a { before it so it can be transparent.

I made a brush in the map, and added the texture to it. I made the brush a func_wall, set the render mode to rransparent, so the number to 255.

When you run the map, the blue is not transparent like it is meant to be. It works with other { textures, like the ladder.

You can upload a fixed file if you work it out.
