if you want to use the alfa channel in the file change : float alfa_col = tex2D(AlfaeSampler,In.coordonate_alfa); with: float alfa_col = (tex2D(AlfaeSampler,In.coordonate_alfa)).a; in the pixel shader
//If you have problems with viewing objects with alfa maps, I made an fx file that you can use with //max so you can see color maps,alfa maps,vertex paint and vertex alfa without the seams. //Just make a text file call it "something.fx" and paste this text in it then open it from max as a //Directx Shader.…
