I have a big problem with the renders. In some projects, when I make render, big white frames appears inside. At the beginning I was thinking just was the gmask. Erase every mask. But the white frames continuous there. Sometimes with antialiasing the frames disappears, or make it more transparent. Other times, when disconnect some layer the white frames go out, but after returns.
I don't know what more thinks I can do. Any suggestion? We are ending a big film, and we are some afraid.
