10- Clicked File/Import/Wavefront OBJ. Import Options: [X] Centered, [X] Percent of standard figure size=100.0, [X] Make polygon normals consistent. All the other options are unchecked. Selected file. D:/Apollo-Headless.obj.

DO NOT CHECK ANY of those import options as they will move/resize the object and so mess up the rigging.

Also do not just use a "zero" pose.
You have to make sure that ALL movement/trans dials of both the hip and the BODY actor are actually ZERO.
Same for ALL morph dials, especially as Apollo has several ERC dials.

The object file must be perfectly zeroed before you export it.
