)

Remarks

Utility function for easily running a TFunctionRef on the RHI thread. Must be invoked from the render thread. If RHI does not run on a separate thread, the TFunction will be executed on the current thread. This method will flush the RHI command list meaning that the function will be executed before ExecuteOnRHIThread returns.
