Merging mask layers in Krita depends on the type of masks and your desired outcome. There's no single "merge masks" button; the process involves combining layers and their associated masks strategically.
Merging Visible Layers and Masks
To merge all visible layers and their associated masks, follow these steps:
- Select all visible layers: Go to
Layer>Select>Visible Layers. - Merge layers: Go to
Layer>Merge with Layer Below. This merges the selected layers sequentially, effectively combining masks as well. This method combines the effects of all masks on the merged layers.
Merging Specific Layers with Masks
For more controlled merging of specific layers with masks, consider these approaches:
-
Right-click merging: Right-click on a layer and select "Flatten Layer." This merges the layer with the layer directly below it, including their masks. Repeat this for all desired layers. This offers granular control, merging layers one at a time.
-
Temporary Group Layer: Create a group layer. Move all layers with masks you want to merge into the group. Then, merge the layers within the group. This method is particularly useful when dealing with complex layer stacks and ensures the combined masks work as intended. The group layer acts as a container to consolidate before the final merge.
-
Converting Masks to Paint Layers: For selection masks, you can convert them to paint layers. This involves duplicating the local selections, converting them into paint layers (right-click > Convert > to Paint Layer), then blending the resulting paint layers.
Considerations
- Transform Masks: Merging layers with transform masks requires careful consideration. Before merging, ensure the transform mask is applied correctly and that the desired transformation is finalized. Merging after transformation retains the effect of the transformation on the combined layer.
- Transparency Masks: Merging layers with transparency masks may require a temporary group layer to ensure proper mask preservation before merging. This method ensures that transparency effects are preserved during the merge.
Example Scenario
Imagine you have three layers: a background, a character, and a shadow layer, each with its own mask. To merge these and maintain the masked areas, group the three layers, then use Layer > Merge Visible. This would combine the background, character, and shadow, preserving their individual masked effects in the resulting merged layer.
