Modifying a Layer's Visibility
Modifying a layer's visibility changes what is shown in the active viewport.
Modify the visibility state of a layer in the Layer Visibility Editor:
To modify the visibility state of a geometry layer, click on the Geometry tab. Find the layer you would like to modify, then click on the icon representing that layer's current visibility state.
To modify the visibility state of a lighting layer, click on the Illumination tab. Find the layer you would like to modify, then click on the icon representing that layer's current visibility state.
This switches the visibility state. If the layer was hidden, it will now be visible. If it was visible, it will now be hidden.
The visibility state icon will change to reflect the new state.
