I create tank destroyer model in blender. When I export model to nif file format. When open in nifskope (right image) I remove niskinpartion, model broke down (left image).
I know that you need to think about the low point, because otherwise the model in civilization is invisible. only when in this model I removed the low partion the model broke.
