I'm wanting to convert the orientation attribute to a rotation attribute. The purpose is so that I can check the attributes coming from unreal and compare. Any idea how to do this?

So, I did a point wrangle:
vector vec = set(0,0,1);
v@rot=qrotate(@orient, vec);

This does convert things to a vector 3. Not sure my unreal data looks like it's matching up exactly, but that's what I needed to see.

what your rot represents is z axis direction of your quaternion, maybe that's what you were after
but in case you wanted euler rotations you can do this:

Just in case anyone runs into a similar issue. Posting the solution I used. Went back to the original unpack and used the cracktransform to directly get the rotation values from the primintrinsics. This worked much better.

matrix m = primintrinsic(0,"packedfulltransform", @ptnum);
@rot=cracktransform(0,0,1,{0,0,0},m);

Thanks tamte, I will also take a look at that as well. Appreciate it.

Brilliant, tamate. Just tried that and it gave me the correct results. Much simpler and can grab it on the fly. Very nice. Thank you.
