Material Expression Speed Tree
Editor Properties: (see get_editor_property/set_editor_property)
accurate_wind_velocities(bool): [Read-Write] Support accurate velocities from wind. This will incur extra cost per vertex.
billboard_threshold(float): [Read-Write] The threshold for triangles to be removed from the bilboard mesh when not facing the camera (0 = none pass, 1 = all pass).
desc(str): [Read-Write] A description that level designers can add (shows in the material editor UI).
geometry_type(SpeedTreeGeometryType): [Read-Write] The type of SpeedTree geometry on which this material will be used
lod_type(SpeedTreeLODType): [Read-Write] The type of LOD to use
wind_type(SpeedTreeWindType): [Read-Write] The type of wind effect used on this tree. This can only go as high as it was in the SpeedTree Modeler, but you can set it to a lower option for lower quality wind and faster rendering.
