Firstly I have no idea what im doing so assume the worst.
In the top section you can see the texture that ive placed in the game as it should look. The texture file is 256x128 and the frame size in wow is 256x128, the lines are 3 pixels with 20 pixel spaces.
As I fiddle around, after a while the texture starts to resemble the latter half and I start to see gaps between bars and textures, things stop lining up properly and I spend about 3 days working backwards trying to find out what the problem is until theres nothing left T.T
I tried tying it to anti aliasing but thats just a wild guess I have no idea. Anyones time would be greatly appreciated.
