* Helios - LYN-3250 - Fixed morph targets for meshes that had multiple materials (#374)
Fixed morph targets for meshes that had multiple materials and were split by AssImp: Recombined them into one mesh in the O3DE scene graph, so the behavior would match FBX SDK.
ATOM-15465: Fix issue with incorrect rotation on models.
* Revert "{LYN-3229} Update AssImp package with latest AssImp 3rd party source changes (#545)"
This reverts commit 06d2050ac4fe6b9d0d0c52e759cf73a9a3f7d3eb.
* bumping version to force assets to reprocess
* Added error reporting for data integrity issues for non-uniform motion data.
* The actual issue was a mismatch between the end times of the morph and the skeletal animations. They need to match in EMotionFX.
* The morph target animation exported a keyframe too much.
