No probs :). I know the fried brain feeling well. All the best

Brain's cutting out on me lately . Thanks again for your detailed Gi expertise . Very much appreciated . Perhaps Arjo will find the time to offer a Post-per/box rendering solution , but I doubt if it's feasible for the bench or video res stuff , as you have pointed out . Multiple instances could easily solve the idle CPU problem with multiple (up to 8) cores , I think . cheers & thanks again garry > Hi David : > > > Basically you need to turn off the safety tab in rendering/post > > settings. > > Thanks for your reply , it tweaked my memory and made me realise > why I gave up on post-processing per box .
