I’ve said it before, and I know that I am repeating myself on this point:
Remeshing is essential when you work with subdivision modifiers.
If you think that remeshing/retopologising is beneath you or that , then maybe you should do the world a favor and stop making SecondLife content.
Or content for any realtime application in fact.
This is the result of Monday/Tuesday: I am far from happy with it, I can see many potentially weak areas and it looks a bit too dense in places where it shouldn’t be. Other than that, reasonable progress I suppose.
