Remarks

Override this method to provide parameters to the GPU (SRV / UAV / Constants / etc) The most common usage will be to provide a single structure which is nested with other parameters. The structure would be declared like this BEGIN_SHADER_PARAMETER_STRUCT(FMyShaderParameters, )SHADER_PARAMETER(float, MyValue)SHADER_PARAMETER_SRV(Buffer, MySRV)END_SHADER_PARAMETER_STRUCT()

And inside the override BuildShaderParameters you would simple add the structure ShaderParametersBuilder.AddNestedStruct();

You should also ensure that AppendCompileHash includes the parameters like this InVisitor->UpdateShaderParameters();

When filling the data inside the set function you would ask for parameters using the same structure. Note: This function is only called on the CDO only not the instance
