I brought over a project with a terrain, and the terrain has many trees that were part of Manufactura K4's Nature Pack. These trees are made with the unity tree creator. Under Unity 4 and Beast, the trees affect the light map. Under Unity 5 and Enlighten, they do not. The trees are configured to cast shadows (Cast Shadows is "On"). The trees do have realtime shadows. Buildings and other objects are casting shadows in the light map. Any thing I can try?
