Hi,
Please double-check the Absolute Rotation values of the ForestPack object. It might be inherited from the used surface, which is not always desirable. If that's not the case, please feel free to send us your scene, and we'll check it. Thank you in advance.
Best regards,
I think it's not about the ForestPack object's rotation values. They're okay. But I found out that it somehow involves a surface geometry that wasn't properly reset with Xform before creating a ForestPack on it. Only after resetting the Xform of the surface geometry, the newly created ForestPacks are okay.
In theory, if I align a ForestPack icon back and make it completely straight by the Y coordinate, it will be fine. But I don't remember having such a problem in ForestPack before.
