Use the LUT preferences to import and list the 1D and 3D LUTs you can use in Smoke. See General Workflow for LUTs.

You can use a hotkey to switch between the first ten LUTs in a 1D LUT list. Press Alt+Shift+1 for the first LUT, Alt+Shift+2 for the second LUT, and Alt+Shift+0 for the tenth LUT in the list.

You can use a hotkey to switch between the first ten LUTs in a 3D LUT list. Press Ctrl+Shift+1 for the first LUT, Ctrl+Shift+2 for the second LUT, and Ctrl+Shift+0 for the tenth LUT in the list.

3D LUT List boxDisplays the list of 3D LUTs that you imported for use in Smoke.

Import buttonOpens the Import LUT browser. Navigate to the 3D LUT file you want to use, and select it to load it to the 3D LUT list.

Delete buttonDeletes the selected LUT from the 3D LUT list.

Delete All buttonDeletes all LUTs from the 3D LUT list.

1D LUT List tabDisplays the list of gamma LUTs that you defined and 1D LUTs that you imported for use in Smoke.

LUT Type boxSelect whether you want to define a gamma LUT or import a 1D LUT file in the current row and assign the selected hotkey.

Import buttonOpens the Import LUT browser. Navigate to the file you want to use, and select it to load it to the 1D LUT list. This button is active when the LUT Type box is set to LUT file.

Value fieldDisplays the gamma value. This field is active when the LUT Type box is set to Gamma.

Delete buttonDeletes the selected gamma or 1D LUTs from the list.

Delete All buttonDeletes all LUTs from the 1D LUT list.

Select buttonApply the selected gamma or 1D LUT.

To define a gamma LUT:

1. Click the 1D LUT tab to display the 1D LUT list.
2. Select the row with the hotkey you want to assign to the gamma LUT.
3. Enter a gamma value in the Value field.

To apply a LUT from the 1D LUT list:

1. Click the 1D LUT tab.
2. Select the row with LUT you want to apply to the display.
3. Click Select.

   The filename of the applied LUT and its assigned hotkey display in blue.

   NoteWhen a ID or gamma LUT is applied it cannot be deleted, unless you click the Delete All button to clear the entire 1D LUT list.

To import a 1D or 3D LUT:

1. Click a tab to display the list for the type of LUT you want to import.
2. Select the row with the hotkey you want to assign to the LUT.
3. If the 1D LUT list is displayed, in the LUT file box, select LUT file.
4. Click the Import button.
5. In the file browser, navigate to the file you want to import.
6. Select the LUT file.

   The LUT file appears in the LUT list in the selected row.
