Regression
Yes
Meshes with Blendshapes have higher memory usage
How to reproduce:
1. Open attached project "2020.2.7f1-BlendshapesMemory.zip"
2. Put "character.fbx" in the scene
3. Open Window -> Analysis -> Memory Profiler
4. Click Capture in the Memory Profiler
5. Open the captured snapshot
Expected result: "Mesh" uses ~27MB
Actual result: "Mesh" uses ~48 MB

- Hinge Joint transforms are reset when toggling the "useMotor" property
- Motion Vector texture reports incorrect Mesh data when Mesh is coming from off-screen
Resolution Note (2021.2.X):
As designed. This was part of a fix to the Profiler that fixed Mesh runtime size reporting in development builds, as previously we would not track some of the mesh data when reporting memory footprint. Furthermore allows for seeing the size difference between read-only/read-write meshes
