I know he has, but even with the most high-end machines, when you do the maths on average render times, how much code they have to write, time taken to search for music tracks, etc, and just how much is involved in posing and lighting the renders and animations, they'd surely have to be living in a Hyperbolic Time Chamber to be able to do all of this by themselves in just 5 months, or they simply don't eat or sleep.
Would be very interesting if DPC did a development stream some day so we can all see just how quickly they work, because if we can see them making about 50 renders in a day, then that would go a long way to dispelling doubt.
That's an interesting question. The way DPC gives his numbers makes it hard to track the number of renders/animations he posed in a given week, but we could make some estimates.
He finished with 3334 static renders and 162 animations. The animations were all posed by 10/2 and the last of the static renders were posed by the following week. If we assume he began posing two weeks after Episode 5 launched, he had a little over 15 weeks to pose everything. Let's say he works 80 hours a week on the game, and devotes 75% of his time to posing. That would give him ~920 hours to pose everything.
We don't know how long it takes to pose a static or animated render, so we will have to settle for some rough bounds. If animations and statics take equally long to pose (which I doubt), he'd have to create a pose every ~15.8 minutes. If we assume animations take 10 times longer than static renders to pose, he would need to pose a static in 11.1 minutes and an animation in ~1 hour 51 minutes.
I have zero experience with animations, so I cannot say how feasible it would be to hit those numbers. If I were to guess, I think it might be doable if the process is largely automated (selecting pre-set poses from a large library and the like). A lot of the statics are basic things, and DPC has been at this for a while. He probably has a good idea of how the characters will look, and just needs to customize certain aspects (like lighting or new clothes) for a given scene.
That said, it's obviously an insanely hardcore workload (pun intended). I still worry about the guy burning out.
