Alright, let’s tackle this sword-and-sheath conundrum! Modeling complex intersections can be tricky, can’t they? Ever tried Boolean operations in ZBrush? They can be a lifesaver. Carving out precise spaces is key, almost surgical. The key detail is the exact matching form. I’d suggest exploring Boolean subtraction in ZBrush, ensuring high-resolution meshes for clean results. Something similar happened when I was designing a custom phone case once; getting the button cutouts to perfectly align took ages – a real learning Slope lesson in precision!
