I just across this post looking for a solution to miss alignment when bone deforming, captured packed prims in a RBD sim. Mops Align sorts this, but also passing everything through a transform pieces sop. MOPS better

Hi CNC
Thanks for the project file, I like the use of the geometry import and stretch to follow the path. very handy thanks. I've used that in the below.
I ended up brute forcing the solution with sops but I'm sure there is a more elegent maths way if anyone is up to the challenge?

The thing that needs solving for this set up is how to make the offset of the camera stay at the same distance (boom arm length) from the path point it is following but stick along the track (fixed axis).
Essentialy calculate the points on a line from a given point at a given distance. you can then look back at the point

I ended up using a distance from geometry node and masking the points out to get the offset. just to be confusing in the image below the cameras pointing in the wrong direction because it reverses when baked.

here's the HIP
