> Layers & blend
1 BIT PIXEL
Stack your art on layers, organize them in groups, and control how each one composites with the layers below.
Layers & groups
Add, reorder, rename, hide and lock layers in the Layers panel. Group layers into folders; a group's opacity and blend apply to all its children as one unit. Long-press a layer for more: duplicate, merge down, scale, or set it as a reference (visible while drawing, left out of exports).
Details & edge cases
- Hiding or locking a group hides or locks everything inside it.
- Reference layers stay visible while you draw but are left out of every export.
- A group's opacity and blend apply to the group as a whole, not to each child on its own.
Blend modes & opacity
Each layer has an opacity slider and a Blend dropdown — 19 modes (Multiply, Screen, Overlay, Add…). The blend changes how the layer mixes with everything beneath it, and it looks identical in the editor and in exports.
Details & edge cases
- Layer opacity and tool opacity stack — a 50% brush on a 50% layer ends up near 25%.
- Hue, Saturation, Color and Luminosity mix using the whole color, not channel-by-channel.
- A blend mode only mixes with the layers below, so the bottom layer has nothing to blend into.
Alpha-lock & clipping
Alpha lock a layer (long-press → Lock alpha) so painting only recolors existing pixels — great for shading without spilling over the edges. A Clipping mask makes a layer show only where the layer below it is opaque.
Details & edge cases
- On an alpha-locked layer you can recolor existing pixels but can't paint into empty areas or change their opacity.
- A clipping mask uses the nearest non-clipped layer below as its base; with no base below, the clipped layer is invisible.
- The eraser does nothing on an alpha-locked layer — its alpha is locked.
