Thanks for your great work.

But when the occupancy gt is used (use_3d_loss=True), NerfHead seems make no contributions.

If I set weight_depth=1.0 and weight_semantic=1.0, the performance drops a lot.
And when weight_depth and weight_semantic both change to 0.1, the performance arise to a normal level, which is comparable to the performance of model when weight_depth and weight_semantic both change to 0.0.
