For anyone who has tried to rig the Solider 76 model, they may have found a weird issue with the animations rig looking sideways. Anyway, I have been trying to find a way to make this work. I sadly didn't have luck with the initial workaround, and while my SFM model logic is limited I think I found a fix.

• Spawn in the Solider 76 model (I am using Speedster's), and set his "rootTransfor - rot" values all to 0 (click on the model's main node, and then on the list of all the possible points, scroll to the end, you'll see it).
  
  
• Then right click on the main root model node again, and click "Show in Element Viewer", "Animation Set"
  
  
• Now expand the "rootTransform" item, and in the value orientation, change the 3rd value to a 0, and press enter (there are a total of 4)

I am going to play around with this a little more. But when I did all this I found the Solider 76 model match up with the rig model (instead of always be like 90 degrees off)
