Another way to create a digital double is to use metahumans from unreal engine and apply the face of the actor on it and export them to Blender, I just did this! your channel content is great!
This is a really well produced BTS video of the work you have done. There's only one thing that I wondered about when I saw it: with all the obvious effort you put in there to make this look real, what was your consideration to make her bounce off the second (lower) branch of the tree instead of the top one. The way her arms stretch out in the dummy shot, it looks as though she would have hit the top branch, so even in the split second you see this shot it registers to me as though she's falling *through* the top branch. But since you've obviously thought about this a lot, I was wondering why you chose to do it like this?
Oh you need reference get it from movie "Ong Bak" Tony Jaa movie, it is in the beginning May be it is more accurate about falling from tree instead of building
I've seen rag dolls with rigid body armatures. Took way too long to rig for me to bother with. I'd be tempted to roto or motion grab all those cool stunt clips Mr Letarte showed but you'd still have to animate to match the shot/storyboard. I liked that you focused more on the principles than the specifics, gave me lots to think about. Cheers.
