The ExposureBias property of the Tonemapping class is used to adjust the exposure level of the tonemapping effect applied to a camera. This property is of type System.Single, representing a floating-point value that modifies the exposure bias.

Note: This property is marked as obsolete, indicating that it may be removed in future versions or replaced by a different mechanism. It is recommended to use alternative properties or methods for exposure adjustment if available.

To use the ExposureBias property, you can get or set its value to adjust the exposure level of the tonemapping effect. However, since it is marked as obsolete, consider using other properties or methods for exposure control.

Example usage:

Tonemapping tonemapping = new Tonemapping();
tonemapping.ExposureBias = 1.5f; // Set the exposure bias to 1.5
float currentBias = tonemapping.ExposureBias; // Retrieve the current exposure bias
