janus problem

[MnKnight1]

Thank you for your work! I found that there was a janus problem in the result of the "teddy bear" example, because the textural inversion was over-fitted to its front view, resulting in not producing the correct rear view, which could lead to janus problems. Will there be such a phenomenon in the official result?
