Here is my BTEX creation wich I use on my hunters. The image shows you the skin in action using a resolution of 1680/1050. I use Skinner to set the viewport so there is no loss of view when using the skin. BTEX has also a Viewport onboard.
Unzip the package and copy the four .tga files into the BTEX folder under Skins. Ingame type "/btex menu" in the chat to go to the configuration menu.
Choose "<CUSTOM SKIN>..."
Type "spunged" in the "set name" box
Select your settings for size/transparency and click: apply skin.
If it don't fit change the size settings. I used a size of 480 on a resolution of 1680/1050 but may vary.
