HD Scene Color Node Code

[Krajca]

Hi, I need to use HD Scene Color Node in my custom node, but I can’t find it’s code anywhere. Has anyone done something similar?

EDIT. or is there any way to execute any node in custom node?

bump?

I would just add an input to your custom node where you input the scene color.

But here.

Unity-Technologies/Graphics/blob/d0473769091ff202422ad13b7b764c7b6a7ef0be/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/ShaderGraphFunctions.hlsl

There is a ‘shadergraph_HDSampleSceneColor’ function.

Which you can find here.

Unity-Technologies/Graphics/blob/3d970023cfcb2d6c105e5ad351bdf746c0b477c9/com.unity.render-pipelines.high-definition/Runtime/ShaderLibrary/ShaderVariables.hlsl

So the code would be like this.

SAMPLE_TEXTURE2D_X_LOD(_ColorPyramidTexture, s_trilinear_clamp_sampler, uv * _RTHandleScaleHistory.xy, lod).rgb;
