Incremental Frame, with moving objects (possible?)

[indigooo]

I am thinking in made a personal project and render it on vray. There will be needed a lot of trees and plants, the only way to do it (almost the most coherent one) is to make clips on crossed planes, with forest pro or ml_trees. Also there are several utilities that will keep the objects looking always to the camera, if i turn off them to not generate GI, and render the imap in incremental, will i have any problem (splotches, sudden dark zones, etc..) and will i gain some time in the process? is that factible?

Thanks in advance

excuse for the bad english :P
