In addition to the native CTF format, applications that use Autodesk Color Management can read several LUT and transform file formats. When imported, these formats are converted to native operators. Autodesk products that support the export of transforms will export them as CTF files.
Supported formats include:
ASC .cdl files are loaded as ASC_CDL operators. The style used by the color transform operator is determined by the SYNCOLOR_DEFAULT_CDL_STYLE environment variable. This can be one of the following values: v1.2_Fwd, v1.2_Rev, noClampFwd, or noClampRev. If this environment variable is undefined, the default is v1.2_Fwd. For more information about these styles, see ASC_CDL.
When a .cdl file is applied to the display, a Look switch is added that allows you to toggle the transform on and off.
The first CDL defined in the file is loaded as an ASC_CDL operator. The style is also determined by the SYNCOLOR_DEFAULT_CDL_STYLE environment variable.
