Locks and Masks

Procreate Pocket offers various ways to modify certain areas of content without affecting others. This gives you the freedom to work fast and experiment with confidence.

Layer Locks

While they are not Masks in the digital art sense, Locks offer an important related function. Layer Locks protect some or all layer from edits. Alpha Locks protect a part of a layer.

Layer Lock

To prevent any accidental changes and edits made to a layer you can lock it. Swipe from right-to-left on any layer or Layer Group, then tap Lock.

Locking a Group will lock all layers in that Group. Unlocking any layer in a Group will unlock the entire Group.

When locked a layer or Group will display a small padlock symbol next to the name. You cannot edit, move, cut, paste, transform, or delete a locked layer. It is completely protected.

To unlock a layer or Group for editing, swipe from right-to-left and tap Unlock.

Alpha Lock

Alpha Lock lets you to lay down a shape or area of artwork, then lock this 'alpha' shape. Once locked, you can only paint or smudge inside the area that already has paint on it - you cannot paint outside of it.

To alpha lock your selected layer, tap on it again with one finger to bring up its layer options. Tap on Alpha Lock to apply it. Tap this option on any alpha-locked layer to disable the alpha lock.

Active Alpha Lock layers display a checkered background in the thumbnail.

Need to touch up an edge, or add to your existing Alpha shape? Turn the Alpha Lock off, make your changes to the artwork, then switch Alpha Lock back on.

Layer Mask

Masking a layer is a great for non-destructive experimentation.

You can modify a Layer Mask to hide or show any part of its parent layer without erasing any content. You can also Lock, Transform, and Copy Masks.

Create

Add a Mask attached to your Primary Layer.

Tap your selected layer to invoke its layer options menu, then tap Mask. Your new Mask will appear attached above the selected layer.

Edit

Edit your Layer Mask by using the Eraser or painting in grayscale.

Layer masks are edited using grayscale, and they are filled with white upon creation, so they reveal everything. Erasing or painting in black hides parts of the layer beneath, and painting in white reveals parts. Varying shades of gray alter the content with corresponding levels of opacity.

When a layer mask is selected as your current layer, choices you make in Colors will ignore hue. This ensures you always paint on a layer mask in grayscale.

Select

Select the layer mask or its parent layer as your current layer for different actions.

When you select a layer mask as your current layer, you can use erase or paint to edit the mask. Selecting the parent layer as your Primary lets you to modify content that sits underneath the mask on that layer.

Selecting either the layer or the mask as the current layer will select the other of the pair as a s econdary layer. This allows you to Transform both at once. If you want to Transform the layer or the mask independently, deselect the other item first.

Move

Move a masked layer without affecting your layer mask.

Tap and hold on the layer mask or its parent layer to pick up both, and drag them elsewhere in your Layers interface. The layer mask will remain attached to its parent layer until you merge or delete it.

Delete

Delete or lock a layer mask.

Like any normal layer, swiping left on a layer mask reveals the lock or delete button.

Layer masks do not have their own Duplicate button, however. Duplicating a masked layer will create a copy of both the layer and the mask.

Clipping Mask

Control the visibility of a layer based on the content of another.

When you activate a Clipping Mask, it clips your active layer to the layer underneath it. The visibility of the clipped layer controls the contents and transparency of the parent layer below.

Create

Turn a layer into a clipping mask from the layer pptions menu.

To turn a layer into a clipping mask, tap on the layer to select it, then tap on it again to bring up layer options. From here, tap Clipping Mask.

Transform

Experiment with the shape and form of your clipping mask using Transform.

Use the Transform tool to move, scale, or distort the content on your parent layer. This changes which parts of the clipped layer will be visible.

Adjust

Play with color, texture and effects on your clipped layer with Adjustments.

Reimagine the appearance of the content on your clipped layer. Explore the power of Adjustments with filters like Opacity, Gaussian Blur, or Liquify.

Move

Pick up and move a clipped layer to change how the content is affected.

Clipping masks differ from layer masks in that they are independent of the layer they affect. You can pick up and move a clipping mask like any normal layer.

When you move a clipping mask's layer order, it will clip to the layer below it. Move a clipped layer to the bottom of your Layers interface, the clipping mask function will deactivate. Move a layer below the deactivated clipping mask and the clipping mask function will reactivate.

Lock, Duplicate, Delete

Control your clipping mask with standard layer options.

All the standard layer actions and layer options are available for clipping masks.

Swipe left on a clipping mask to reveal buttons for Lock, Duplicate, and Delete.

Deactivate

Toggle clipping masks on and off.

To toggle the clipped status of a layer, tap on the clipping mask to select it, tap again to invoke its layer options menu, then tap the Clipping Mask button.
