The Dunning-Kruger effect bit my ass 🫤 Despite feeling pretty confident with retopology of simple models, a little more detailed character showed my skill deficiency here. But well, thats life 😅 Skills exist to be learned! Whole life is one long learning experience, and I'm not scared of learning new stuff.
I need to learn more about correct a shoulder 3D topology, so it both deforms nicely and subdivision do not smooth out all details. And probably the same for a neck.
And what do to when there is drastic mismatch in vertex count in loops which need to be connected. For simple, low-detailed models the problem simply doesn't exist, but it starts to show for mid-detailed models. Redirecting loops in random directions causes weird folds and wrinkles when combined with subdivision.
