It's easy enough to assign the custom poses to the hands, and they do work, by snapping immediately to the new pose.
I would, however, like to animate the hands adopting the new custom pose (from their current pose). Has anyone managed to do this, or can Oculus please advise on the best way to accomplish?
Another avatar related question regarding changing to the opaque render queue. The page linked above mentions a "Use Transparent Render Queue" option. Where is this option located? Should it be on one of the avatar components or in a material/shader or something? I can't find it anywhere!
