Questions on aligning scene predictions to GT scene #30

Thanks for your amazing work!
I've been trying to replace CUT3R backbone and found out that Human3R's scene prediction aligns well with the GT depth while other metric-depth estimation like Depth-Anything 3 fails to do so. I think this alignment is critical to train SMPL's translation parameter. Is there any idea how you managed to align the scene points to the GT?
