1. Importing animated models in Lumion

It is not possible to import vertex animations, morph animations, skinned animations or bone animations in Lumion.

Upcoming versions of Lumion will not be able to import vertex, morph, skin or bone animations either.

If you try to import 3D people/animals from websites such as TurboSquid, Anima, 3DPeople, RenderPeople, Mixamo, Daz3d and Axyz Design, or animated trees from Plant Factory or SpeedTree, they will be imported as static models. 3D people/animals will either be in the socalled T-pose or in the pose that they are in at frame 0 of the animation. 

1.1: However, it is possible to import move/rotate/scale animations. Please see this article for more information:
