Trouble copying texture to Wad

[Royal_Sir]

There is only one thing between me and releasing my 3-level wad.

METLSL05.

The problem is, no matter what solutions I attempt, the image is crappy ingame.

Here's what its supposed to look like:


What it looks like in-game:


Any help would be appreciated.

In Slade, make sure the format is Graphic (Flat). Right click, select Graphic, and then select Convert To ... and in the drop-down on top, select Doom Flat (Paletted). Also, it must be exactly 64x64 in size. Also, it needs to be in between FF_START and FF_END tags (empty lumps that tell the engine that the lumps in between are flats (for floors and ceilings), which are handled differently than textures for walls.
