Development Summary

Importing FBX Assets

The image below shows a simple monkey mesh. As shown in the image, the transform of the mesh is at default values and exported as is.

The image below shows the same asset imported to Unity. As you can see on the right side of the image, the rotation values are at 0 but the mesh is facing down. This is because the Unity engine uses Y-axis as the vertical axis while Blender uses Z-axis as the vertical axis.

Each 3D modelling tool uses different axis orientation so it is important to check the assets before using them.
