I have a fairly complicate file that in the animate camera, one frame the trees are on, the next they are not, and the one after that they are on again. I have several forest objects, and they all turn off near and far in the display. It renders this way as well.
I have tried to turn off the occlude by camera, density, and merging the xref. Nothing seems to work. Any ideas?
I have attached the two frames so you can see what i mean.
