Ouuch. Nice Link, by the way.
Simple recommandations, I'm afraid:
-Is Buldozer working properly ? Try to load other stuff.
-Do not forget to put the texture in the addon's folder. There are other ways, but for Single-Usual-AddonMaking, I recommand this way.
-Is the folder at the root, && the same root as the Bull ? Otherwise expect trouble. Once again, not mandatory but it's foolproof.
-Also not mandatory but safer: Use TexView to convert, it's a way to check your Texture after all, so why not ? Convert, && save @ the right place...
Also, check the Option-menu in Oxygen, tick "autoconvert Gif&Tga": This way is NOT foolproof, but works for importing trouble-free textures.
-By sometimes, just GerOff O2 && fire it again. I swear that 1 times out ouf ten, it's curing the mess.
I say 1 out of ten, okay, I didn't say it WAS the cure for all of you out there crying after non-displaying textures.
usually, textures won't appear because:
1. Wrong size format
2. Ill-located file
3. AlphaChannel-mess or wrong type format, but this is more specific.[/b]
Mostly I say.
Also check this topic for a funny view on my last misadventure regarding Texturing:
