Learn how to import 3D files with the Z-axis as the up axis
There is a good chance that this is caused by your authoring software using the Z-axis as the up axis convention.
We've added a naming convention that will allow you to import obj, fbx, dae, and 3ds files with the z-axis as the up axis:
Simply add "_Z-UP" at the end of your filename.
For example a file named "3dScan.obj" would need to be renamed to "3dScan_Z-UP.obj"
