So having an issue with my avatar, everything for the most part works but I notice when I move my arms (this is with FBT but I assume with just 3 points tracking it'd be the same) my avatar's upper arms like..."snap" in place when I reach out my arms as far as I can stretch them in real life. I'm not sure why my avatar's arms snap like that. Does this mean my avatar's arms are too short and are not 1:1 with my real arm length? I know there's that video that shows how to adjust avatar proportions in blender, but I'm not even sure what the problem is to begin with I'm guessing the arms are just too short?
