I think he shoots 4-5 renders for the same scene. Like a real director.He didn't go into too many details about reversing the process and work with his old GFXs. His explanation was more about troubleshooting and issues with the high-end GFXs. He replaced GFXs with other high-end GFX until he found the compatible ones that worked with DAZ. To me, the ideal would have been reversing the rig back to the original GFX and work on building another rig with the high-end GFX so he didn't have downtime. I don't know why he didn't build a second rig in the first place. Also, I think he sold the old GFXs to help offset the cost of the new ones.
His only communication to me about the render farm idea was that he looked into it, and it wasn't going to work for him. I have no clue why it wouldn't work for him, but that's what he told me. I can only assume he didn't want to risk his CS/Images to fall into someone else's hands.
Word on the street is Sophia's getting a little tired of L&P. That he's pretentious, that he's despotic. Sophia says he's complicated to work with. Gossip.
