Lock layers to prevent accidental changes to their position, scale or to avoid interfering with other layers while editing. Note that layer locking is done per scene — you’ll need to lock layers individually in each scene where you want them to stay fixed.

Lock a layer

1. Right-click the layer in the scene editor.
2. Select Lock layer. You won’t be able to select, move, or scale this layer in the scene editor.
3. Once locked, you’ll see a lock icon next to the layer name in the Layers section of the Properties panel.
   

Lock an extended layer

Locking a layer only applies to the current scene. If the layer extends across multiple scenes, you’ll need to lock it in each one or from the Timeline.

1. Select the entire extended layer by double-clicking it in the Timeline.
2. Lock the layer using Option + L (Mac) or Alt + L (Windows).

Unlock a layer

You won't be able to select a locked layer from the scene editor, so you'll need to unlock it from the Properties panel.

1. Select the scene containing the locked layer.
2. In the Properties panel, find the Layers section, then click the lock icon to unlock the layer.
