a simple technique to create a free arm from body rig that actually looks attached.i don’t have any experience with rigging so if you know a better technique it would be very nice of you to share it.
I also don’t know if there is a name for this type of character rigging that can move their hands all over their body, usually you use them on very stylized cartoony characters. a very simple way would be to just use round corner shader but that way if you look at it from the side, the arm-body intersection looks very sharp, so instead we can use this technique to blend the arm into the body. never tried it myself but I think it will look the best with characters that have fur on top.
sorry for not including any voice over or subtitle instruction, I create these videos very fast just to answer someone’s questions.
