DracoUnity 3.0.0
Changed
DracoMeshLoader
's coordinate space conversion from right-hand (like in glTF) to left-hand (Unity) changed. Now this is performed by inverting the X-axis (before the Z-axis was inverted). Compared to the previous behaviour, meshes are rotated 180° along the up-axis (Y). This was done to better conform to the glTF specification.
That's it. 3.0.0 is essentially 2.0.0 with a different coordinate system conversion, justifying a major version bump to not confuse users.
