More that I meant, that I don’t believe the engine will give him the answer he wants. I wasn’t trying to be insulting, but illuminating.
Sometimes, there really isn’t a hard diagnostic that will tell you what you want. Particularly if what is part of the equation is open to user-customization. It’s not so straight forward to say it costs X to render to the RVT because you don’t know if the compiler will be able to pack channels, pack math, etc, based on what the user is doing.
So! I hope I didn’t come across as ill-tempered, far from it.
