Shader question

[JeViCo]

Hello everyone!

I have a simple shader:

texture Tex0;

technique paint {
    pass P0 {
        Texture[0] = Tex0;
    }
}

For example i have several images on 1 texture but background is black (even with transparent render target). How can i fix it? I want to replace black background with another texture

Do you mean you want to have alpha blending enabled? That requires slightly more than this simple shader, namely, AlphaBlendEnable, SrcBlend and DestBlend and I believe that might require a pixel shader.
