7. Applying Look Files, Lighting, & AOVs
Matt Barker of Intraware concludes the series by applying look files and setting up lighting in Katana.
In the video:
• You can use a LookFileAssign node to select the look file.
• Add a LookFileResolve node to tell Katana that it should unpack and apply the look file operations.
• Matt uses Show Incoming Scene on a GafferThree node to show every light that is upstream in the node graph.
• In the GafferThree node parameters, right-click on a light and select Adopt for Editing to reveal editable parameters for the light.
• Matt adds a .tdl image to a 3Delight environment light.
• Use Pin Visible Leaves in the scene graph to maintain item visibility in the viewer.
• Instead of clicking around the scene graph to select a light, you can set sync selection to in/out to highlight the light in the scene graph when it is selected in the GafferThree parameters tab.
• Edit the 3Delight settings using the DlSettings node.
• To speed up the viewer, turn on speed boost in the DlSettings parameters to halve the resolution and reduce sampling.
• 3Delight offers a simplified approach to AOVs in Katana.
• Click the Add button in the Image Layers section of the DlSettings node to add AOVs.
• Turn on Save IDs as Cryptomatte to convert ID passes to Cryptomatte versions.
• Set ImageFilename and Image Format in the DLSettings parameters (so no need for a RenderOutputDefine node).
• The Render node lists the output paths.
• To use both the 3Delight and the Katana monitor renderer, open Preferences, select 3Delight and set renderView to both.
• You can use the 3Delight renderer to view all the selected AOVs. You can also open the mixer using Ctrl+X, which gives you control over some useful render settings.
• By default, the Render node allows you to do preview, live, or disk rendering.
• You can render out, or bake out, different look files.
