The normals I see both in your tutorial and mine don't have negative sign behind them. Why do you put a negative sign behind them in meta file?

got the reason for negative normals from https://github.com/liuyuan-pal/Gen6D/issues/7#issuecomment-1191033327 The normal is shown in the left-bottom panel. Note that the normal is opposite to the Z+ direction (up), so the Z+ direction for the object is (-0.04148,-0.13305,-0.99024)
