ReGradePlusHeader

iMMERSE Ultimate: ReGrade + is a commercial-level color-correction suite for ReShade, inspired by industry-standard tools. It eliminates the need to leave the game for detailed adjustments, allowing real-time color correction with an intuitive UI. This makes it a seamless experience for users, especially those knowledgeable in Color Theory, Photography, and Image Post-Processing.

warning

ReGrade + requires the Addon Support build of ReShade to function properly, otherwise the screen will be black when the shader is enabled.


Setup and Configuration:

Enabling ReGrade +

Before adjusting parameters, move the "ReGrade +" tab to a separate window in the ReShade/Game UI. This controls the entire shader and lets you tweak other effects while viewing the results in real-time. Enabling the shader alone won't activate it. If any component is not running, the Addon/Shader Window will indicate it:
