Hello,
I need your help in the file LightGridCommon.ush
I’m trying to customize the light component by adding some stuff in it and in the forward rendering, i need to change thos file.
I need to add my custom new line in this :
FLocalLightData GetLocalLightData(uint GridIndex, uint EyeIndex)
{
FLocalLightData Result;
if (EyeIndex == 0)
{
uint LocalLightIndex = CulledLightDataGrid[GridIndex];
uint LocalLightBaseIndex = LocalLightIndex * LOCAL_LIGHT_DATA_STRIDE;
Result.LightPositionAndInvRadius = asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 0]);
Result.LightColorAndFalloffExponent = asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 1]);
Result.LightDirection = asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 2].xyz);
Result.ShadowMask = ForwardLocalLightBuffer[LocalLightBaseIndex + 2].w;
Result.SpotAngles = asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 3].xyz);
Result.SourceRadiusPacked = ForwardLocalLightBuffer[LocalLightBaseIndex + 3].w;
Result.LightTangentAndSoftSourceRadius = asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 4]);
}
...
return Result;
}
Where asfloat(ForwardLocalLightBuffer[LocalLightBaseIndex + 0]); get the value in the .cpp or .h ?
I found it in the BasePassRendering.h but i can’t find anything with the Index +0 or Index +1 …
The Idea here is adding a boolean in the result to play with it in the light system
Thank you
