Unity 动态修改URP后处理参数 Volume

引用命名空间

using UnityEngine.Rendering;
using UnityEngine.Rendering.Universal;

以景深为例

Volume volume = GameObject.Find("Global Volume").GetComponent();;
public DepthOfFieldMode modeType = DepthOfFieldMode.Gaussian;    

DepthOfField dof;
//检测是否添加了景深
if (volume.profile.TryGet(out dof))
{
	dof.active = DepthOfField;
	
	dof.mode = new DepthOfFieldModeParameter(modeType, Mode);
	
	//true 对应的是景深下 模式前边的是否启用的开关
	MinFloatParameter gaussianStartValue = new MinFloatParameter(startValue, 0, true);
	dof.gaussianStart = gaussianStartValue;
	
	
	MinFloatParameter gaussianEndValue = new MinFloatParameter(endValue, 0, true);
	dof.gaussianEnd = gaussianEndValue;
	
	
	ClampedFloatParameter gaussianMaxRadiusValue = new ClampedFloatParameter(MaxRadiusValue, 0.5f, 1.5f, true);
	dof.gaussianMaxRadius = gaussianMaxRadiusValue;
	
	
	BoolParameter gaussianhighQualitySamplingValue = new BoolParameter(HighQualitySampingValue, true);
	dof.highQualitySampling = gaussianhighQualitySamplingValue;
 }
