Hi,
When using a surface, I would suggest you to always double check it's local coordinates (your surface coordinates should correspond with intended Forest object orientation). For example a plane created in Front view will work differently with Forest objects as another one created in Perspective / Top view. Generally, when using surface(s), it's handy to apply the
Reset XForm utility on it to "reset" it's local coordinates as any "scaled surface(s)" Forest will inherit this scale (and that's not always desirable).
As mentioned above, applying the
Reset XForm utility over that surface to reset its local coordinates & scale should fix it. To rebuild the Forest object, use the the
Update surfaces data button or feel free to mark the
Auto check-box (to
Update surface data automatically - this may add a performance hit for complex surfaces).
If the problem persist, please feel free to
send us your scene to analyse it here.
Best regards,
