I do not use Limit to Visibility, ever, so that's not the culprit.
As mentioned yesterday - FP 7.0.6 freezes 3ds max, or at least some of the forest pack objects - grass elements specifically.
Reverting to 6.3.1 is the only solution for me to keep work going.
For the record the forest pack object was initially done in FP 6.3.0 then copied the object between scenes. With version 7.0.5 was good enough but encountered the slow interactive update inside camera.
Reverted from 7.0.5 to 6.3.1 - no such issue. Now trying hard what could be the problem with 7.0.6. but I'd rather spend the time pushing the project forward, so have to revert once again to 6.3.1.
Are there any compatibility issues between 6.x.x and 7.x.x. ?
