Had to ping Brian Karis who pointed me to FPackedNormal which is the struct used to store normals for rendering. Looks like its simply storing each channel as an 8bit uint.

So the data is there since the rawmesh data is storing the normal as an FVector, but it may be pretty difficult to change the render data to use that due to the number of places it is used.

DXGI_FORMAT_R10G10B10A2_UNORM would go a long way to fix this without increasing storage.(assuming that alpha channel isn’t used right now.)
