Hi,

Thanks for your excellent work! Here is a question about the data processing.

I found objects in Objaverse dataset are not in the same initial pose, especially the rotation angle. I guess that's why your code have the args of rotaion_y and rotation_x. How do you deal with the angle problem during training? Since it is impossible to set rotation manually during training.

Do you do some preprocess steps to make the rotations uniform?

Hi, thanks for your interest. That's a good question.

We didn't have any preprocessing steps as we trained our lightcontrolnet only on random 2D renderings. Thus, there was no need for us to specify a canonical rotation for every object.
