One of the imported objects has it’s mesh in animation sequence down scaled by like 10 times compared to it’s normal size. This causes the object to scale down when using this animation sequence
(animation sequence at bottom left)
I made this model in blender and never had problem like this.
Hi, this can happen either when the scene used to animate is out of scale with the engine’s 1u=1centimeter scale OR when there’s a scaled object in the hierarchy of the bone in question. Check also the import settings in ue4, and the export settings in the animation software for unit transforms.
