Trying to get that sun bloom effect that David originally posted, to work whit layers and zoom. I've got it to work with layers whit some formulas I found from the forums but cannot figure out how to implement zoom.
Here is the edited CAP
Maybe there is better way to do this but since I assume OR condition is't working correctly this seems to work.
Edit:Actually it seems to be quite a heavy hit to performance. At least in my case.
