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.
To export a LUT, do the following:
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.
4 Select a LUT format at the bottom of the file browser window.
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 pop-up menu list.
TIP: This is one way to move LUTs between viewers or to and from the Color Curves
node or any other LUT Editor in Fusion.
LUT Files
Any supported LUT files in the LUTs folder can be used by choosing them either from the LUT
pop-up menu or the viewer’s contextual menu. This includes 1D and 3D LUTs such as Fusion’s
.lut, .alut and .alut3 formats, as well as .cube .shlut, .look, .3dl, and .itx formats. This is a
convenient way to access standard format LUT files for different projects.
Settings and Macros
Since LUTs are a form of color correction, you can also use any node, macro, or group of nodes
as a viewer LUT.
To use a node, group, or macro as a viewer LUT, do the following:
1 Select the node, group, or macro.
2 Right-click over the selected node, and then choose Settings > Save As from the menu.
