Description

Thank you for contributing to Armory!

**Description**
Rotation is not exported correctly.
The rotation direction in blender is different from the exported korm preview.

maybe related:
https://github.com/armory3d/armory/issues/2167

**To Reproduce**
Animate transformation over multiple axes or more complex transformation mode like quaternions, then export/preview in korm/armory3d

**Expected behavior**
Exported rotation should be identical to the model/animation in blender

**System**
Blender: 3.3.7
Armory: 2023.5.0
OS: Windows 11 Home 22H2 22621.1702
Graphics card: AMD Ryzen 5 5500U with Radeon Graphics 2.10 GHz

**Test File**

Research direction

Start with the attached armory-rotation-plygrd.zip and compare the Blender animation with its exported korm/Armory3D preview, focusing on multi-axis and quaternion transformations. Read the related issue #2167 for context. Done means exported rotation matches the Blender model and animation.
