Regrettably, in Blender 3.6 and certain earlier iterations, there are rigging issues. While importing vehicles via The MEGA Fleet add-on does function in prior Blender versions, you’ll have to strip away the rigging component and re-rig the vehicle manually. This is because the MEGA Fleet add-on was crafted in Blender 4.0, utilizing a customized rigging script. Please be aware that we cannot offer support for utilizing the MEGA Fleet add-on in Blender versions earlier than 4.0.
