Black screen on iOS after adding second target

[blackmonster]

Hi all.
I'm trying to implement RTT. Created a camera, added a viewport and got a black screen.
Even if i add a second viewport to the window the situation is the same.
Just render nothing, trying to setup multiple viewports and receive a black screen just after adding the second one
Please help

Some code would be helpful. Have you checked out the tutorial that implements a mini screen? That works just fine on iOS.
