Mesh normalization/scaling issue

[HouIP]

Hi, thanks for the code release and really cool work!

I generated some scenes with the provided dataset. Then rendered them using render_existing_scene from blender_render.py. I noticed that some meshes from the dataset aren't normalized: their scales seem off and their rotations look incorrect.

I’ve attached a test case JSON (living_room.json) along with the rendered image as a reference.
Is there a normalization step I need to apply?

Thanks!
