Hi Dick, lovely clouds as always and good to see you here.  The Vue 8 clouds do seem to have much more realism. 

Just ordered Vue 8 and have used various AP settings although setting of 1 makes sense.  Maybe you can give an example of the differences you are referring to?

I wonder though if using very large real world sizes increases processing time though?  I did a very large scale scene where populating seemed to take forever.  Maybe it was due to Vue only using a single core for population?  It would seem size shouldn't matter but only the number of population items....but I don't know.
