Alpha to multiple textures during render

Fuzzy Mage · 2007-05-14T11:31:14

I'm trying to create a radar to display for a UI that will have a grid that moves with the player as he walks. Since I am using a square grid texture to create this tile effect, I need to alpha out anything that isn't inside the radar frame. The problem I'm having is that not only do I have somehow apply an alpha map to this image during render, I've got to apply alpha maps to multiply images that were not created with alpha maps. I'm seeking some sort of explanation to solve my dilemma, or even better solution to my issue. The project is using managed directx in C#. For a better explanation, this picture shows the frame that will show the visible grid, the four grid images that will be moving up and left, and the opaque areas are what I do not want to be visible.

Just learned that my opacity is no longer working. Alpha is fine though. Happen to know what renderstate I need to activate to make my objects see-through?
