You turn layers on and off in After Effects by using the Video switch (eye icon) located in the Timeline panel.
Here's a more detailed breakdown:
Understanding the Video Switch
The Video switch, represented by an eye icon in the Timeline panel next to each layer, controls the visibility of that layer in the Composition panel.
- Visible: When the eye icon is active (highlighted), the layer is visible in your composition.
- Invisible: When the eye icon is deactivated (not highlighted), the layer is hidden from view in your composition.
Steps to Toggle Layer Visibility:
- Locate the Timeline Panel: Make sure the Timeline panel is open and active in your After Effects workspace.
- Find the Layer: Identify the layer you want to turn on or off in the Timeline.
- Toggle the Video Switch: Click the eye icon (Video switch) next to the layer name. Clicking it will toggle the layer's visibility on or off.
Advanced Tips for Managing Layer Visibility:
- Hiding Multiple Layers: You can quickly hide or show multiple layers by clicking and dragging the Video switch (eye icon) up or down the column in the Timeline. This will toggle the visibility of all layers you drag across.
- Showing Only Selected Layers:
- Select the layers you want to make visible.
- Go to
Layer > Switches > Hide Other Video. This will hide all layers except the ones you've selected.
- Showing All Layers: Go to
Layer > Switches > Show All Video. This will ensure that all layers that are not intentionally hidden are visible, regardless of prior selections. - Solo Layer: If you want to isolate a layer and hide all the others, use the Solo switch (small circle icon) next to the Video switch in the Timeline panel. Clicking the Solo switch for a layer will temporarily make only that layer visible.
- Using Expressions: You can even control layer visibility with expressions, linking it to other properties or conditions within your composition. This is an advanced technique but provides a great deal of flexibility.
