That was an amazing explanation.
I can relate to everything you said, since I experimented a lot with rigging and weight painting. I know what you mean by the 2 bones affecting 1 vertex, and also the 0.01 value thing, I’ve stumbled upon this problem at some point. I still have a lot of learning and experience to gain, but what you did there put me in the right direction and motivates me a lot. There are so many methods and workflows possible, sometimes as a newbie, you just don’t know if you’re losing your time. Now I understand a bit more how skeletons work, and how it’s handled in Blender and UE4.
Thanks again for this very nice explanation ! o7
