CurvesUE is a color grading tool built into the Unreal Editor. Draw Master and RGB curves, adjust color with HSL and HSV controls, and bake the result without leaving the engine.

Three bake backends

• LUT: Creates a 3D LUT in Unreal native 256 x 16 format, ready for the Color Grading slot.

• HDR: Uses a material-based workflow with Scene Color After DOF.

• Native: Approximates the curves with Unreal built-in post-process settings.

Each backend has its own live preview, so what you see while editing matches what you bake. Versioned outputs prevent older bakes from being overwritten. The preview disables when you bake and returns when you edit, avoiding double grading.

Point insertion works like a traditional curves editor: adding a point does not reshape the curve until you move it.

Open it from Window > Grading Curves Tool.
