Semi transparent camera?

[wheretheidivides]

I have a mini map on a camera on the upper right part of the screen. Another camera is full screen. Is there a way to set the alpha or transparency of the smaller map camera so it is only 1/2 transparent?

i never did this, but i am pretty sur you have to "print" each frame what you mini map camera is viewing into a texture.

then you could do anything with your texture shader (transparency in your case).
