I\'ve been working on transition effects and experienced an issue with the number of cameras you can mask.
The Sync Mask accepts an integer, limiting expressions ( 2 ^ Camera id ) to 32 bits.
Any ideas how to use up the other 32 bits? 64 bit mask possible?
Run this code and move your mouse up and down. The green line only shows up on camera 32 (Actually, the green line is the real scene)
The other way to produce special effects using different views is to render scene manually with one camera with however many settings you need; but it would be good to know if 64 bit masks are possible. Sync Mask will not take a double integer.
