Have your ever payed attention to the environment floor's texture of the angry bots demo which comes with unity3D ? here is the texture : (why this atlas texture looks like this with less alpha ? )
This Texture name is EnvironmentFloorTiles_A and I Wonder how they have created this and why they had to this ? I had opened this in a new standard material in 3DS max and applied this to a plane with UV's modified , by a miracle it was mapped on the plane as a chromatic texture. Perhaps there is a relation to the alpha channel. but I don't why and what?

Finally I had found the answer ! if we erase or make a png transparent , we don't remove the RGB channel , but we are removing the alpha channel of that which is embedded on it ! So if we erase and transparent a png , we make that transparent pixel color black in it's alpha channel , very long thread I had started contains the full answer :
