Returns

true if the function was queued, false if RHI does not use a separate thread, or if it's bypassed, in which case, the function has already been executed.

Parameters

Parameter	Description
Function	the Function to be invoked on the RHI thread. When executed, it will get the current FRHICommandList instance passed in as its sole argument.
