Speedtree: Variation of same tree without duplicating materials on import

Hi All,

In SpeedTree Modeller I create several variations of the same tree. The only thing I do is clicking the randomize button and save the tree under a different name. After this I import the model in the Unreal Editor and with each import every material also gets imported again. The only thing different is the shape of the mesh; the rest of the materials/textures/normal maps are all the same. Is there a way for the Unreal Editor (or SpeedTree modeller) to recognize they are the same so the won’t get importing again?

Regards,
Olivier

Open them all up in the Speedtree compiler and compile them together. This prevents them from importing the textures again.
After that just hook the same materials up to all of the trees and remove the rest of the materials (or uncheck make materials when importing all but one).
