I believe I aleady told you this: hire a professional mocap studio, save yourself from 3 years of work and learning.
Put your time and money on properly creating a custom character that you own the rights to.
First of all, the tech is junk. Thats a factual opinion given by several others with years of expereince in character design. Adjusting a bone structure based on variables is nothing new, its been around for ages. Adjusting animations based on whatever is nothing new which has been around for ages as well.
Unawareness doesn’t make something “amazing” to the rest of the industry.
Second of all, its absolutely not free. Read the licensing for it. Its only “free” when used in specific ways.
This may not matter to joe small making a game that will never see the light of day, but it matters to anyone actually intending to eventually publish. Particularly if you won’t be using this sorry excuse of an engine due to its constanst performance loss.
Third of all,
All that metahumans have been doing since release is to devaluate the actual artists behind character design.
“Oh you don’t need to hire a character designer, just use a metahuman. You won’t even need to know how to create a rig or how to create animations! Heck, you won’t even need to know what haircards are or what the tris count of a mesh should be!”…
