Help with alpha blending transparency

[joaoNfsMw]

(english is not my first language so expect some english errors)
i was trying to do a mod for AC (Private use only) when i noticed that when i use the Alpha blend mode , most of the textures i put on it become transparent, i already tried to put it in the alpha test mode but the NM's wouldn't work then. Also i had some shading problem with the textures that worked with Alpha blend

If you use alphablend mode, you also need istransparent on every object that uses it.
