Unreal Engine 4.9 Preview

[=;343690]
After starting up my project in 4.9 again I actually get the whole log spammed with this:

LogStaticMesh:Warning: Adjacency information not built for static mesh with a material that requires it. Using default material instead.
Material: /Game/Assets/Buildings/MainBuilding/M_Wood_Floor_Walnut_Polished.M_Wood_Floor_Walnut_Polished
StaticMesh: /Game/Assets/Buildings/MainBuilding/Main_Building_Single.Main_Building_Single

I can actually cut down the material to only a texture sample which goes into the base color, but I still get the warning in the log and the default material on the mesh. Once I disable “flat tesselation” and set it to “no tesselation” and apply it the problem disappears.

Hey -

Can you let me know if you are attempting to apply this material to a Custom Mesh (Procedurally Generated) or an imported mesh?

Thank You -
