Look into Updating Assimp #56
Description
https://github.com/Saalvage/AssimpNetter
https://www.nuget.org/packages/AssimpNetter
Update Assimp to use a newer package version. This is purely for maintenance purposes, as dealing with legacy code, especially C# that isn't on the same .NET version as the parent project can cause some issues. This shouldn't change any functionality, It'll just make managing the code base easier.
The current version of Assimp also exhibits some issues when attempting to import geometry, mainly issues with rotation values
(AI_CONFIG_IMPORT_COLLADA_USE_COLLADA_NAMES needs to be enabled in order for collada import to function correctly)
Collada Extraction - Works
FBX Extraction - Unknown
Collada Import - Works
FBX Import - Works
EDIT: There are some issues with FBX import where the marker positions are broken. This needs to be looked into some more.
