I create a model with 3dmax and export it as fbx.
When the model in max, the model’s center is at foot.
But when I import to unity, the model’s center is at back.
Why???
It’s not a problem???
potentially your model is child in a chierarchy and that resets / overwrites its position upon export.
Unity doesn’t change anything, it will use the hierarchy as it came in.
Use ResetXForm in max before exporting to get correct orientations. Unity will sometimes rotate by 90 degrees as well but it will work fine.
Ths a lot.
It indeed is not a problem. It’s pivot and center controller problem
