So basically I have a model that consists of two separate objects, knight and sword. Models are animated and rigged (Blender), some bones inside the Knight model are animated with Inverse Kinematics. The Sword is just parented to the hand bone and follows its moves. The problem is that when I import my model to Marmoset,…
Make sure that you're exporting all of the objects in the scene, including the skeleton. If only exporting selected objects the rig may not be included, which could cause the animation data to not import as expected.
