Exporting a scene causes all objects to move to 0, 0, 0 coordinate.

[destin-v]

Describe the bug

When exporting a generated scene to USDC, all of the objects are placed in the 0, 0, 0 position. I discovered this bug just by following the tutorial on installation, hello world, and exporting.

Steps to Reproduce

See below.

What version of the code were you using?

Release: v1.12.2
Git Commit: 59a2574

What command did you run?

# on  Mac x86_64 (Intel)
brew install wget cmake llvm open-mpi libomp glm glew zlib

git clone https://github.com/princeton-vl/infinigen.git
cd infinigen
conda create --name infinigen python=3.11
conda activate infinigen

# Full install (Terrain & OpenGL-GT enabled, needed for Infinigen-Nature HelloWorld)
pip install -e ".[terrain,vis]"

# Make dirs
mkdir outputs

# Generate a scene layout
python -m infinigen_examples.generate_nature --seed 0 --task coarse -g desert.gin simple.gin --output_folder outputs/hello_world/coarse

# Populate unique assets
python -m infinigen_examples.generate_nature --seed 0 --task populate fine_terrain -g desert.gin simple.gin --input_folder outputs/hello_world/coarse --output_folder outputs/hello_world/fine

# NOTE
# -----------------------------------------------------------------------------
# At this point I can open up Blender and view the desert generated file.  
# I see that there are boxes spread out across the map which are placeholders 
# for the generators needed for things like bush, cactus, etc.  The next step is 
# where things fail.  When I export the file and view the USDC it places all of 
# the objects in the 0,0,0 position.  This does not match the original fine Blender
# file found in outputs/hello_world/fine.
# -----------------------------------------------------------------------------
python -m infinigen.tools.export --input_folder outputs/hello_world/fine --output_folder outputs/desert -f usdc -r 1024
