Original guy deleted his post so I'm guessing things got sorted out, but I do just want to throw something out there for anyone using that scene because the original poster said something that I figured would be a problem (but I kinda couldn't fix it without messing up my original scene).
The penis might be phasing through the stomach because there's timeline nodes to bend shaft ~3-5 as far back as possible when it's inside, but I couldn't make it TOO far back without messing up how it looks in Laevatain (if I went too far back you could tell it was bending drastically in the scene). You might need to manually edit each of those nodes in your timeline if you can't get things to work by adjusting folders. With that being said, that should be expected with any animated scene with penetration...it's going to be harder when you stray from the original character heights/dimensions. You have a much shorter chara in that scene relative to Laevatain, so things are gonna be broken. Honestly, in my experience, I just keep the scene censored and let it be misaligned a bit and let the censor gap the difference for your eyes (I typically do that for shota versions of my scenes that I don't release).
Also, there's a readme in my scenes going forward with advice I give on potential issues with replacing charas in my scenes. I see it's not open in the original screenshot......hint hint
