When extruding Eevee 3D models, start with precise offset/depth settings in the Extrude tool and use face/edge selection to maintain mesh quality for Eevee’s real-time shading.
Eevee relies on consistent topology to avoid artifacts—vertex extrusion creates messy results, so stick to faces/edges. Enable “Auto Smooth” in the Normals tab to keep extruded surfaces smooth without extra geometry, which helps Eevee render cleanly.
If you’re new to extruding in Eevee, practice with a simple cube first: test “Region” vs “Individual” Extrude modes, check the Eevee viewport as you work, and tweak settings gradually to avoid mistakes.
