re texture help please

[Deleted518329User]

HI, im currently making a xenomorpth mod ( the aliens from aliens vs preditor) anyway Im fairly new to blender, ive managed to get a model done, basing it off the ghoul model (so I didnt have to do new animations) but cant work out how to re texture it.

When I use nifscope and add a texturing property, the creature becomes invisible in the GECK and in game

I have followed all tutorials for blender texturing, but although the new texture appears in blender, when I save and view the creature in game or in the geck, its back at the original texture.

I think I need to use blender as the texture seems to be embedded into the creature

anyway if someone could help that would be great.

thanks
