Well...not really but I feel where you're coming from there, Shane. I mean, it's apparently still being taught to people as a viable starting position, as time in galleries and sites like Turbosquid seem to suggest.  Still, it is definitely not the more natural of the two positions, that's not even a debate in my mind. lol. I just wish Walk Designer worked better with it. In Poser's defense, we included the arm out adjustment in Walk Designer some time back for models in non-T start positions or odd body types where the arms may potentially criss-cross during the walk cycle.  So it's something you could do for Poser you just have to let people know that they'll need to adjust the arms in Walk Designer when using it to help with walk/run cycles.

 I think there's also a lot of mocap data that starts in the T-Pose. Not sure how much that impacts the need for that position to still be viable.
