I'm having a big problem for my app.
I have a render to texture camera, I use to to make a zoom effect, the thing is that while my render to texture camera is deactivated, I can see the video background, but as soon as I active my rneder to texture camera, I loose the video background and it became black and like with a don't clear flag.
This render to texture is mandatory for my app, i've read something about using background to texture technique to avoid this problem, but i don't have things clear in my mind :P sorry
Could some if you tell me a solution for this, or a step by step (or near to that) solution for the background access texture solution to the black background?
I'm using Unity 3.5.7 for iOS.
Cheers and thanks in advance.
