There are a variety of ways to create and use different viewer LUTs in Fusion. You can save LUTs when you save viewer settings, you can import LUTs that have been exported from Fusion or other applications, and you can open any one of the various supported LUT file types. In addition, you can use the standard nodes in Fusion to create macros, which can then be saved and used as a LUT.
LUT Settings
The most straightforward way to save a LUT you have created using the Fusion View LUT Editor is to use the LUT > Save menu found in the viewer contextual menu. The settings are saved as an ASCII file with the extension .viewlut in the LUTs folder. Any files with this extension found in that folder will appear in the Image LUT menus for ease of loading. You can also load the settings that are not found in the menu by choosing LUT > Load from the viewer’s contextual menu.
Using Viewer Settings
If you’ve modified a LUT, choosing Settings > Save New from the viewer’s contextual menu will save all the viewer’s settings, including all LUT curves and gain/gamma values. You can save these under different names, and each settings file can be reloaded at any time by choosing Settings > filename from the viewer’s contextual menu. Choosing Save Default from the same menu will make these settings the standard for all new comps.
Using LUT Curves
The Viewer LUT Edit dialog can be used to import and export LUT curves. You can export the LUT curves as either ASCII or Saved format. The ASCII (.alut) file format is useful for sharing LUT curves with other software, whereas the Saved (.lut) file format is preferred for Fusion, as it is more compact, accurate, and allows further editing.
1 Click the viewer LUT button to enable it.
2 Click the viewer LUT menu, and then choose Edit.
3 Right-click on the LUT Curve Editor, and then choose Export LUT.

5 Enter a name for the LUT and click Save.

The Import LUT option will load LUT files back into the Curve Editor, or alternatively, if the file has been saved in Fusion’s LUTs folder, it will appear in the LUT drop-down menu list.
