**Short description of error**
Sculpting - When you export a sculpted mesh and you reimport it details are missing till you press clear custom split normals.
For example if I try to bake the high poly to substance painter I don't have the details of my sculpted mesh.
**Exact steps for others to reproduce the error**
- Open default sculpting file -> sculpt a mesh
{F12957258}
- Export it in FBX format with default settings
- Open default scene -> delete everything -> import the FBX file
(this is what you see when you re-import it)
{F12957261}
the sculpted are shows on the side view
{F12957263}
if you hit clear custom split normals the details will show up!
