Per instance custom data and Material Layers issue

Per instance custom data and Material Layers issue

UDN
Steps to Reproduce

1. Download the Licensee repro and open (link in comments).
2. Observe the trees, and the random bend in them.
3. Open the material /Content/BFGame/MaterialLibrary/MaterialV2/M_V2MasterOpaque
4. Delete the PerInstanceCustomData expression and hit "Apply".
5. Observe that all the trees in the level stand straight.
6. Open the Material Layer /Content/BFGame/MaterialLibrary/MaterialV2/Layers/ML_VertexBend. Observe it uses PerInstanceCustomData to calculate the bend, but only gets the data correctly when the base material has a PerInstanceCustomData expression.
