Question I am new to HDRP and idk why costume function breaks when I put a value in.

Idk if I am doing something wrong but my function breaks the moment I put a value in.


Sub Graph With values on zero:

Source For Main Light (Called "Lighting"):

void MainLight_half(float3 WorldPos, out float3 Direction, out float3 Color,

    out float DistanceAtten, out float ShadowAtten)

{

#ifdef SHADERGRAPH_PREVIEW

    Direction = normalize(float3(0.5h, 0.5h, 0.25h));

    Color = float3(1.0h, 1.0h, 1.0h);

    DistanceAtten = 1.0h;

    ShadowAtten = 1.0h;

#else

#if SHADOWS_SCREEN

    float4 clipPos = TransformWorldToHClip(WorldPos);

    float4 shadowCoord = ComputeScreenPos(clipPos);

#else

    float4 shadowCoord = TransformWorldToShadowCoord(WorldPos);

#endif

    Light mainLight;

    GetMainLight(shadowCoord, out mainLight);

    Direction = mainLight.direction;

    Color = mainLight.color;

    DistanceAtten = mainLight.distanceAttenuation;

    ShadowAtten = mainLight.shadowAttenuation;

#endif

}

I think it’s because you only define the half variant, you might also need to define the float variant if your graph is not using half precision only.
