How to Use the 3D Color LUT Generator (.cube & Hald CLUT)
Choose a Cinematic Preset or Custom Parameters
Select one of our calibrated color profiles (such as Teal & Orange or Kodak Portra) or start from scratch.
Inspect Real-Time Preview & 3D RGB Lattice
Drag the split comparison slider over sample images or your uploaded photo, and rotate the 3D RGB lattice to observe color volume deformation.
Select Grid Resolution
Pick 16x16x16 for mobile/lightweight shaders, 32x32x32 for standard Unreal Engine / Unity games, or 64x64x64 for cinematic video editing.
Download .CUBE or Hald CLUT PNG
Click "Download .CUBE File" to import directly into DaVinci Resolve, Premiere Pro, or Unreal Engine Post Process Volumes.

Frequently Asked Questions
What is a 3D LUT (.cube) and how does it work?
A 3D Look-Up Table (LUT) is a mathematical 3D grid that remaps input RGB color coordinates to new output RGB color coordinates. Unlike 1D LUTs which only adjust individual color channels independently, 3D LUTs can handle complex cross-channel transformations, allowing precise film emulation, split-toning, and saturation remapping without introducing banding.
How do I use a .cube file in Unreal Engine 5?
In Unreal Engine 5, import your downloaded .cube file into the Content Browser. Unreal will generate a Color Grading LUT texture asset. Open your Post Process Volume or Camera actor, enable "Color Grading LUT", and assign the texture to apply the cinematic grade in real time.
How do I apply this 3D LUT in DaVinci Resolve or Premiere Pro?
In DaVinci Resolve, open Project Settings -> Color Management -> Open LUT Folder, paste your .cube file, and click Update Lists. In Adobe Premiere Pro, select your clip or adjustment layer, open the Lumetri Color panel, and choose "Browse..." under Creative Look to select your .cube file.
What is a Hald CLUT and why is it useful?
A Hald CLUT is a 2D image representation of a 3D color cube (typically 512x512 pixels for level 8). It allows software like OBS Studio, Photoshop, and game engines that lack native .cube parsers to perform 3D color grading via a simple 2D texture lookup.
Are my uploaded images or color grades sent to any server?
No. All color grading calculations, canvas pixel processing, 3D WebGL rendering, and file compilation occur entirely inside your browser memory. No data is ever transmitted to an external server.
