can someone just upload the texture you used i cant get it

Invisible textures are easy in GIMP.

Add an alpha channel (LAYER -> TRANSPARENCY -> ADD ALPHA CHANNEL)

Use the eraser tool & anywhere that has a chequerboard pattern will be transparent.

When saving only use PNG, TGA (with RLE off) or GIF (GIF sucks though).

Remember that unless you have working shaders with transparency turned on the blank areas will be black.

when i go to layer first of all i dont find TRANSPARENCY...but did find ADD ALPHA TO CHANNEL but it doesnt allow me to click on it...
