This is the result of a few hours work tonight:
I arrived to the conclusion that it was easier applying a cheap Occlusion map than re-texturing the original model.
Still I think the ship looks too dark. It looks fine in S3D, but then in game looks darker. Not sure how to change that. I've tried different material attributes in S3D, I've tried making the textures brighter... nothing seems to make much difference
