Use this option to enable or disable multi-pass rendering.
Channels
The Channels drop-down list displays the layers that may be included in the multi-layer rendering. It
also contains various relevant commands. Use the Channels drop-down list to add layers to or remove
layers from the selection list. The items in the Channels drop-down list are:
Add Image Layers
Adds to the selection list all image layers that form the composite image. These layers are: Ambient,
Diffuse, Specular, Shadow, Reection, Refraction, Atmosphere and Atmosphere (Multiply). All the
other image layers (see ‘The layers’, below) may be used for visual effects but are not actually part of
the composite image.
If you have the Advanced Render module installed, Global illumination and Caustics layers are also
added to the selection list by this command.
Add Material Layers, Add All
These commands are useful to plugin developers only.
Remove Selected
To select a layer, click its name in the selection list. To add a layer to those
already selected, Shift-click or Ctrl-click the layer’s name.
Removes the selected layers from the list.
Remove All
Empties the selection list.
Blend Channel
Creates a blended layer. For example, you can blend Shadow, Global illumination and Caustics as a
single layer. After choosing this command, a dialog opens. Enable the channels you want to blend
and click OK.
