I've got a node tree that calculated all the way to the bottom. When I select any node from the tree, it recalculates all the nodes even if I did change any settings. I't been doing that every-single time I select or view a node that was already calculated. I'm about to flip my desk!!
I noticed that when I remove $F in a channel, it stops the problem. But I never played with the timeline so I still don't get why I had the problem with $F...
