Introduction

Renders can be separated into layers, to composite them back together afterwards.

Some example usages are applying compositing effects to characters separately, blurring the background and foreground layers separately for depth of field, or rendering different lighting variations of the same scene.

Using View Layers can also save you from having to re-render your entire image after each change, allowing you to instead re-render only the layer(s) that you have altered.

View Layers

View Layers.

In the top of the screen there is a list of all the View Layers in the active scene.

Name

The name of the active view layer, click to edit the name.

Add View Layer

Will add a new view layer to the active scene.

New

Adds a new view layer.

Copy Settings

Adds a new view layer with all the settings of current view layer.

Blank

Adds a new view layer with all collections disabled.

Remove View Layer

Will remove the selected view layer from the active scene.

Note

A scene must have at least one view layer.

Usage

Each Render Layer has an associated set of Collections. Objects which are on one of the associated collections are shown in that Render Layer, as long as that collection is also visible.

Warning

Only the objects in visible Scene Layers will be rendered. So, if only Collection 1 is visible and your Render Layer set specifies to render only Collections 2 and 3, nothing will be rendered.

Collections

Per collection you can adjust the way how the render engine needs to render the objects inside. Based on the render engine different options can be set.

Collection/View layer settings.

Disable from View Layer

Remove this collection from the active view layer. Objects that are only in this collection will not be rendered for the active view layer. This is useful to sometimes leave out some object influence for a particular view layer.

Enable in View Layer

Add this collection to the active view layer. Objects inside the collection will be rendered with the active view layer.

Set Indirect Only

Objects inside this collection will only contribute to the final image indirectly through shadows and reflections.

Clear Indirect Only

Clear the Indirect Only flag. Objects inside this collection will contribute normally to the final image.

Set Holdout

Objects inside this collection will generate a holdout/mask in the active view layer.

Clear Holdout

Clear the Set Holdout flag.
