A crash occurs when changing/setting the LOD Group of a SpeedTree asset within the Static Mesh editor.
Regression?
Yes, this crash does not occur in the 4.13.2 binary release.
1. Download and Open attached project.
2. Open the Broadleaf Desktop static mesh.
3. Set the LOD Group to 'Large Prop'
Outcome Crash occurs.
Expected No crash occurs and the mesh is assigned to that LOD Group.
