Layer system (layers, groups, clipping masks, layer masks, blend modes)

Organize layers, groups, masks, and blend modes so you can edit a digital painting without damaging earlier work.

What it is

Organize related elements into named groups and separate layers. Keep line art, flats, shadows, highlights, textures, and UI text on layers you can control independently.

Use a layer mask, a black-and-white map that hides or reveals pixels, to adjust edges, cutouts, and fades without erasing. Use a clipping mask to constrain shading, color, or texture to the shape of the layer below.

Choose blend modes for a specific purpose. Multiply can support shadows, Add/Linear Dodge or Screen can support light effects, and Overlay or Soft Light can support tinting. Combine blend modes with masks and groups when you need to adjust lighting later. Merge stable layers or paint directly when a larger layer stack would add unnecessary complexity.

Why it matters

A structured layer system makes color changes, element moves, revisions, and file handoffs easier to manage. Unnamed or overly complex stacks can slow edits, hide mistakes, and make blend-mode effects harder to correct.

You can check it when

• ✓Open an older file and locate its editable elements through logical groups and named layers.
• ✓Adjust edges, cutouts, or fades with layer masks or clipping masks, and change the color scheme or lighting by editing key layers.
• ✓Explain why a layer uses Multiply, Screen, or Overlay, then compare the painting with those layers toggled on and off.
