Overview
Photography-style grading curves inside Unreal.
CurvesUE provides a professional curve-based grading workflow similar to familiar photography-editing tools, but integrated directly into Unreal Editor.
Quick start

- Enable the plugin from Edit > Plugins by searching for CurvesUE.
- Restart Unreal Engine.
- Open Window > Grading Curves Tool.

- Drag points to adjust the grade.
- Switch between RED, GREEN and BLUE channels as needed.
- Use BAKE LUT to save the result as an asset.

Technical notes
Preview and baked formats
- The preview uses a 256 × 1 1D LUT updated in real time.
- Baked LUTs use a standard 16 × 16 × 16 3D format represented as a 256 × 16 unwrapped texture.
- The tool is compatible with Unreal post-process features.
- The editor tool itself is editor-only; baked LUTs are intended for runtime use.

Workflow tips
Good starting habits

- Switch to Smooth mode for more organic curve shapes.
- Bake to a LUT for final project performance.
- Use descriptive LUT names such as LUT_Cinematic_Warm.
