I've got an animated 3D model with two sets of animated furniture in 3dsMax. The sets of furniture are instanced. Both the geometry and animations are the same. When I upload an exported fbx only one set of animated furniture is shown in Sketchfab. Looking at the messages above the published model it says that some animations are redundant and have been dropped. When I pick the "static" option from the animations list in sketchfab, both sets of furniture appear. This means the geometry is actually uploaded.
Is there a way to avoid this and have Sketchfab show both animated models?
