looks abit more plastic, than the native through the model it self is pretty good.
shading highly depends on where its previewed
Very nice model - would increase lag for lower-end machines however, due to polygon increase.
Is it compatible with final boss' pack?
well, 600 polys is not that much, all the non native swords and weapons have polycoutn around that number
i dont know what final boss' pack does exactly, so i cant answer that
