Hi,

You can tweak alignment and rotation under Leaves & Flowers (https://docs.itoosoft.com/forestpack/forest-ivy/leaves-rollout) > Align mode (Branch Normal > Branch Direction / Perpendicular), then fine-tune it with the Rotation settings. Increasing the Growth > Surf. Offset will also lift the leaves from the surface. I hope this helps.

Best regards,

I think one of the biggest issues I'm having is that the ivy treats some geometry like the normals are flipped, when in fact the normals are fine.  A quick reset xform seems to fix it

If you’re having this kind of problem, you can use xView > Face Orientation to identify any flipped faces.

Well that's exactly the problem, there were no flipped faces.

I'll try and recreate a video where this happens
