P.S: I am working on a 2d point and click adventure game. See my other thread.

I've got an image and an alpha mask. How can I use the alpha mask for that image?

I've tried using a Texture Processor and set it as the Content Processor for the original image and it works great.

But now I can't draw the full image. It will always use the alpha mask.

Also, is the best way to accomplish this?

BTW, someone suggested me to use a Depth buffer. How do they work?

Thanks

Are you using pixel shaders? In a pixel shader you would pass both textures in and use the mask texture to determin the color of the pixel selected from your base image. You could add a variable to be passed in that would determin if you want to mask or not. This way you could have it both ways.
