After some pretty good feedback from a few of you, and a special thanks to
@lilbug for putting in a bit of extra legwork, I went ahead and added back Divining Rod to help with some alignment issues. I am really only using it for insertion halfway through though, because I don't care much for how Divining Rod handles BJs/HJs. It also doesn't always look the best at extreme angles, which the cowgirl section of this scene definitely has.
While I was in there, I updated the final handjob animation at the end to more reliably grab hold. YMMV, but it performed a lot better in my testing over here.
@vermilliondx also mentioned some alignment issues with the cowgirl section using other looks. I tried a couple of my looks over here after the updates, including a much shorter, more voluptuous,
red-headed Elf you may remember from my last scene, and she had no trouble at all. Hopefully this has fixed the issue with other looks! I ran through Hazel's morphs, just to be sure, and the only one in there that might be worth modifying if you try your own look is that Hazel has a 0.24 Height morph adjustment. It's not a lot, but if you're having issues with that insertion about halfway through, it could be worth adjusting your look by this amount.
Thanks again for the feedback, to those who provided it. I hope these small improvements are helpful!
