Can the active LUT combine 1D LUTs and 3D LUTs?

Hi steve
Can the colorspace preload 1D LUT + 3D LUT or a 1+3+1 combination in the patch window?
It seems I can only add 3D LUTs in the active LUT, not 1D LUTs, nor any combination of them.

If you want to 'Combine' LUTs you would use the LUT Adjustment tools.
Also remember 1D LUTs are always extracted from original 3D LUTs.

Thanks for the reply.
It seems my version isn't up to date enough to use LUT adjustments.
Also, when you say "1D LUTs are always extracted from original 3D LUTs,"
does that mean 1D LUTs are calculated from the initial small 3D LUT that models the display's nonlinearity?
Or does Color Science first compute a massive 3D LUT and then extract 1D LUTs from it?

If you have a lower license level you will not have LUT Adjustment tools.
Also see the LUT Generation Size information in the User Guides.
That explains about the differences in LUTs, 1D/3D and sizes.
