Rotate to Vector / Forward Direction in Copy POP

POPs
1

I’m attempting go copy a line along the X axis onto the points of a circle (in POPs) to create a ring of outward-facing lines.
It seems like the “Rotate to Vector: Forward Direction” parameter is being ignored.

When attempting the same thing using instancing, the behavior at least changes when the corresponding parameter is changed (though it’s still not why I’m trying for).

Am I using it incorrectly or is there a bug?

Hi Tommy,

Indeed it looks like the Forward direction param is currently being ignored, thank you for the report, we’ll fix it for the next release.
Otherwise not sure what you’re trying for but the way to interpret this parameter is, it will align the Forward direction of your geo (so +Z by default and always +Z on Copy POP currently since broken) with the Rotate To Vector.
And one thing to keep in mind is if the Rotate To Vector and the Up Vector are aligned, no rotation occurs, so it’s recommended to have a per point Up that perpendicular, otherwise you might need to add a small offset so it’s not aligned anymore.

The Forward Direction parameter being ignored will be fixed in builds 2023.31605+
Copy POP will have the same behavior as geo comp instancing, let me know if it’s unclear!

Ah ok. That makes sense. I wasn’t accounting for the up vector.

Thanks for the fix!
