I have this hand model found in this link https://www.dropbox.com/s/u364uyifpw0ca7d/hand.blend?dl=0 and I want to animate it to include all the different sign language movements. I’m asking if anyone could help me do this as I’m new to blender and this will take huge amount of time, where I believe experts here can assist me to do it in a short time.
Might want to post in the volunteer work forum if you want most of this done for you.
Other than that…
You’ll need to get very familiar with the NLA editor so you can create actions and quickly chain the various hand gesture movements used in sign language. (But might want to start with basic rigging if you haven’t already. Plenty of stuff on that.)
You need to create Pose Library for each sign. That way to animate, all you do is to recall each pose and keyframe the sequence to form words.
