In Maya, when you bring a FBX (maya template) from AccuRig the geo is rotated forward if its 180 cm or more (6 ft or more).
If it is 2 cm (tiny), then the object is NOT rotated forward but you can see that the skeleton is rotated -90 and
It also generates v_none for every geo you use in the rig and are hidden but rotated forward.
I also included the root rig with its -90 setting in the transformation node.

If you wanted to create blendshapes after the fact, the rotation would be a problem.

What are the V_none files for?
Why is the rig rotated.

It does this for FBX files whose up axis is Y and Z.
