C, Hard work! I just load main.pz3 then 1) delete half of objects -> save part1.pz3. Then load again main.pz3 2) delete the other objects -> save part2.pz3. Yes I know it very 'painfull' jobs (I have scene where is 10 girls ... and lot of other stuff -> at least 5 parts). Shade offer one light automatically ... so you have add more by youself. Anyhow the rendering time is main benefit (only able to use one extra PC in network, in pro no limit) Janne
