AtomRender

AtomRender

The renderer – a.k.a. the boss

AtomRender is the drop-in replacement for Nuke’s built-in ScanlineRender node. It offers higher quality, speed and unique advanced rendering features achievable only with the AtomKraft toolset.

You can use it in the same way as it provides the same inputs:

• ‘cam’, for a Camera node
• ‘geo/scn’, for a Scene node
• ‘bg’, for a generic image node (i.e. a Constant node)

The ouptut of an AtomRender node are pixels stored in many output channels, which are visible in the channel list of the Viewer node wired to AtomRender.

The position of AtomRender in the Nuke node Graph is at the end of the 3D chain, so after scene and camera:

AtomRender outputs a long list of output channels which you can access by pressing the ‘Channels’ button in the viewer UI, or for example with the ‘Shuffle’ node wired after AtomRender.

AtomRender interprets the builtin Nuke materials (the ones under the 3D> Shaders icon menu, including the RenderMan ones) in two modes (you can set this in the Shading tab):

1. Physically plausible mode (default, and recommended)
2. Nuke ScanlineRender mode (the ScanlineRender compatibility mode)

Depending on which mode you select shading and lighting will behave slightly different.

You should only use Nuke ScanlineRender mode for previously made scenes where maintaining the original look is more important than an improved physical plausible behavior of lights & materials.

For all new scenes we strongly recommend the physically plausible mode.
