Thank you for your suggestion @Konrad
I looked around and found a note now that snapshots are experimental supported at Rhino6 and by V-Ray Next batch tool. I have luck, it works. I need to save a snapshot for each layer state before and than it works. During a first run the lens effects and curve controls was not applied, but after I reload and enabled the frame buffer post tools this works also.
Only one strange effect: I created 19 snapshots and saved my project file. I need a very long time to save and doubled the file size from 600MB to 1200MB. @nathanletwory Is it something what you could check please? Or who is the right man to help here?
