Maybe, maybe! How would I know, never having seen any material on the
subject I could compare it to? If anybody has a nice flowing algorithm that
is not "strange" I would be very interested in hearing about it!

How would you have expected the flowing algorithm to work?

Sorry, I'm going for a 100% generic solution so I won't make any HF specific
workarounds. But I don't think that's where the problem is anyway.

The OldLocation_rotated is irrelevant using my improved algorithm, as the
trace ray is not shot from there.
