P: Ability to use 3D LUTs

[Rovanpera]

I'd love to get the ability to use 3D LUTs in Lightroom, now that those can be created in Photoshop cc 2014.

Thank you John_R_Ellis,

Indeed, it has been improved, but I consider it is still not implemented yet:

I would have liked to apply a LUT (without preliminary steps), in addition to my FujiFilm camera profile.

Non-destructive, WYSIWYG, Amount slider, ... as in ON1, Aurora HDR, DXO, Photoshop, ...

The ACR LUT profiles are non-destructive with an amount slider, but they do require that preliminary one-time step of converting the LUT to the profile.

Also, what color space are your LUTs?  If they're common video LUTs, then most likely they're in Rec 709, which ACR doesn't support -- add your opinion and vote to this feature request:

Convert .cube LUT file to LightRoom custom profile: (workaround)
(Based on Youtube Tutorial: https://youtu.be/Kexd__B_nts)
- Edit photo in Photoshop (smart object)
- Add Filter: Camera Raw Filter
Camera Raw Filter dialog
- Presets (Shift+P)
- Alt + Click "Create Preset"
- Give name
- Check "Color Lookup Table"
- Select .cube LUT file.
- OK to save this preset --> 
The .XMP file is saved in C:\Users\YourUserName\AppData\Roaming\Adobe\CameraRaw\Settings\
- Cancel, Exit PS without saving.
- Restart LRc
- Your LUT should now be available in LRc Develop - Basic/Profile

There's an additional step: After selecting the .cube, you need to select the color space of the LUT.
