And you will see most of the new textures have a white halo around them. The textures are pretty raw as far as transparencies and shadows are concerned.

Adjusting AlphaTestVal in the mat file should lose the halo.Also a layer from the alpha mask coloured dark grey (or anything but white) should help blend the transparency edges.

MCycle skin was tricky with all the spokes, but this worked -
