Hay I was using unity to make a character jointed hand bu as I started
to put them together as a group then the started stretching across the map
or one time I imported a Blender file and it
was all stretched out Has this ever happened to you?
Yep, it happened once in 3ds max, I just set it to editable mesh (from editable poly), and it was okay.
Not once, which means you’ve done something wrong.
As long as the model is done right in blender and exported as fbx I almost never experience problems with the model, check what settings and modifiers you have used in blender, sometimes you can change something and mess up the export.
Make sure you applied rotation and scale in Blender’s Object mode.
