Please let me know is there a way to apply alpha to a mesh or plane in m3g file.As i am new to m3g i am not able to apply alpha .Basically i am new to m3g and i need to rotate a sprite in all directions in 2d game,but the .m3g file becomes too big.So i was thinking if it is possible to apply a texture to a plane (as i dont need all 3 dimensions) and then rotate that plane .But the problem is that i can't apply transparency to plane.So please let me know is it possible what i am thinking????
