Hi all, I want to scatter some cliff assets on terrain slopes. I
used the nodes heightfield_scatter and scatter and scatteralign.

In the Houdini viewport, the cliff assets are correctly positioned, but after passing them through the Houdini engine to the UE, they are displayed incorrectly in the UE.

I suspect that the "orient" or "N" attribute of the points is causing the problem, but I have not been able to solve it personally.

I can't tell which one is wrong now. Thanks for your help!
