You can convert the colour space of the output shots from Log to Lin or vice versa. Whether you are outputting in Log or Lin
colour space, you have several options for setting the LUT used on output. You can:
- Use the default colour mapping. The default mapping differs according to the colour architecture used on the project (as set
in the Grade menu).

- Create a LUT.
- Select an output LUT from a list of those made available in Lustre.
- Use the current viewing LUT. The colour mapping settings made in the Render Output menu are taken into account with the current
viewing LUT. See Rendering with the Viewing LUT.
The output colour space and colour mapping affect the image you see on the monitor. These settings are saved in the output
buffer, which is applied to the output on the monitor after the viewing LUT and monitor.calib correction (if used) are applied. For this reason, when working on shots prior to rendering, it is recommended that you set
the output colour space to that set for the grade colour architecture in the Grade menu, and set the output colour mapping
to Default.
To set output colour space and colour mapping options:
- Access the Render Output menu.
- Enable either Log or Lin.
- Do one of the following:
- Enable Default to use the default colour mapping.
- Disable Default and either create a LUT or select one, as shown in the following procedures.
To create an output LUT:
- Access the Render Output menu.
- Make sure Default is disabled.
- Set the Black and White values.
- Set the Gamma and Film Gamma values (for Lin colour space output only).
NoteIf needed, you can reset these values to their default settings by clicking the Reset button and confirming.
To select an output LUT:
- Access the Render Output menu.
- Make sure Default is disabled.
- Enable Use Custom Output LUT.
A list of available 1D LUTs and 3D LUTs is enabled.
NoteThe LUTs displayed in the list are all located in the C:\Program Files\Autodesk\Lustre <version_number>\luts folder, if running the Windows version of Lustre, and in the/usr/autodesk/lustre_<version_number>/luts directory, if running the Linux version of Lustre.
- Select a custom LUT from the list.
The image is updated.
NoteIf you are using background rendering, place the LUT on all render nodes in the /usr/autodesk/lustre_<version_number>/lut/ directory.
