Reflection Probe Node

Description

Provides access to the nearest Reflection Probe to the object. Requires Normal and View Direction to sample the probe. You can achieve a blurring effect by sampling at a different Level of Detail using the LOD input.

Note: The behavior of this Node is undefined globally. Shader Graph does not define the function of the node. Instead, each Render Pipeline defines what HLSL code to execute for this Node.

Different Render Pipelines may produce different results. If you're building a shader in one Render Pipeline that you want to use in both, try checking it in both pipelines before production. A Node might be defined in one Render Pipeline and undefined in the other. If this Node is undefined, it returns 0 (black).

Unity Render Pipelines Support

  • Universal Render Pipeline

The High Definition Render Pipeline does not support this Node.

Ports

Name Direction Type Binding Description
View Dir Input Vector 3 View Direction (object space) Mesh's view direction
Normal Input Vector 3 Normal (object space) Mesh's normal vector
LOD Input Float None Level of detail for sampling
Out Output Vector 3 None Output color value

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_ReflectionProbe_float(float3 ViewDir, float3 Normal, float LOD, out float3 Out)
{
    Out = SHADERGRAPH_REFLECTION_PROBE(ViewDir, Normal, LOD);
}
