Nice job on the density work. First, pick a single, clean reference seam for each pair of mirrored parts—no half‑cuts or arbitrary splits. Use the knife tool to lay a line exactly along the symmetry axis, then duplicate that cut on the mirrored side. Make sure the angle between the two is zero; any slight offset will throw the texel grid off. After you unwrap, lock the scale and orientation of each face before you apply any baking. If you need to add a seam for a complex edge, keep it straight and as short as possible—ideally on a flat area that doesn’t affect the visual flow. Finally, run a quick check in UV layout: the faces should line up like a perfect pair of eyes. No shortcuts, no auto‑map. That’s the only way to keep the density consistent.

Glad you’re tightening up the cuts. Just remember, even a tiny misaligned line can throw off the whole grid, so keep your knife steady and double‑check the axis each time. Once you lock it, the bake will thank you. Good luck—don’t let the seams play tricks.

Good luck—remember, a single off‑kilter seam can ruin an otherwise perfect map. Keep that knife straight and the symmetry true. Happy unwrapping.
