I started a forum post about this but I haven’t received any responses, thought I’d try to boost exposure to the issue using this place.
Link to forum post (It just reads the same as below).
I am trying to make a character put their hands on a nearby surface.
I have done the IK, so the hand actually moves to the surface. I also have the surface normal vector of the surface at the point where I want the hand to be going to.
How do I convert this surface normal into the correct Rotator for the hand?
I tried using RotationFromXVector, Rotation from X, Y and Z. None of them will line up to make the palm face the surface.
Any help appreciated. Thanks.
Managed to get the angle I want using “Make Rot from XY” by putting the surface normal into the Y axis, and setting the X-axis as default.
I wish these “make rot from XY” functions were available in C++. If anyone knows how to get them, let me know.

Do you have a tutorial on this??? I’ve looked at the 3 screenshots. (I’m an animator, so blueprints aren’t my specialty, hehe).

you’ll need to include the Kismet Math library.
FRotator RotFromXY = UKismetMathLibrary::MakeRotFromXY(X, Y);
This library contains all of the rotator functions you’re used to using in blueprint.
