All trait positions are locked by default. Click Edit beside a trait or choose it from the Selected trait dropdown to unlock only that trait. Lock it again after adjustment, or use Reset to original to restore X/Y 0, scale 1, and rotation 0. Use “None / Skip layer” to temporarily hide any non-Background layer in the preview. Each trait now includes a thumbnail for quick visual identification. Trait names can be edited directly in the Layers list or in this editor and are saved immediately. Every trait has independent X/Y, scale, rotation, and a four-tier rarity setting. Common / Uncommon / Rare / Legendary map to relative weights 100 / 40 / 15 / 5, and rarity changes save immediately. OpenSea rarity is still determined from the final published trait frequencies.
