Non-destructive editing — flattening/merging intentionally

Organize and merge layers so you can adjust or repair a painting without repainting settled areas.

What it is

Non-destructive editing uses layers, masks, and blend modes to keep paint adjustable. Merge or flatten layers when you intend to lock in their contents.

Keep separate elements, such as the character, background, and effects, in their own groups. Use masks for revisions, and place color adjustments or glows on separate layers. Merge settled areas into a simpler structure when appropriate.

Name and order layers so you can locate them later. Duplicate or snapshot important stages before major changes, giving you a fallback without keeping unnecessary layers.

Why it matters

This structure makes color changes, design revisions, and handoffs easier to manage. Weak control can lead to extensive repainting or a large, difficult-to-navigate file.

You can check it when

• ✓You can locate the layers for character colors, background colors, and lighting in an existing painting without extensive repainting.
• ✓Before a major change, you duplicate or snapshot the relevant layers and can compare versions or restore the earlier state.
