Importing a custom 3d scanned scene in Replicator Composer

Hello!
I was following the Replicator Composer tutorial to generate synthetic data. I managed to import a USD model of the object on which I would like to train detection. However, when I imported a custom scenario_model that came from a scene scan using an iPhone, I got only a black background in the generated images after running the script. The object was rendered correctly, but the rest of the scene is invisible. I was able to import the scene model in Isaac Sim, and it was displayed correctly, but it was invisible in the generated images using Replicator Composer. I used the warehouse.yaml as a baseline.
Could you please point me in the direction of how I can turn a custom scene scan into a model that is usable by Replicator Composer?
