PLEASE HAVE THE VFX SUPERVISOR on set when you are shooting something which involves VFX
than paying him or her extra hundreds fixing the mistakes in post on top of the effects...
Yes, even when you know how to shoot the vfx shot, you might not notice the leaks of the problems since you will be busy focusing on rest of your stuffs or you might think that what you've done is good enough to do the effects on.
THINK ABOUT IT :)
