[1.10.2] Render item for IBakedModel

I have IBakedModel, but item for it renders like flat item with emo-texture. I see getOverrides method in IBakedModel and i see that this method need ItemOverrideList. I create class that extends ItemOverrideList and return Collections.<ItemOverride>emptyList() in constuctor and override handleItemState in it, but i don't know how to return my IBakedModel in it, so instead of flat emo-textured item i get my block with IBakedModel.
