Does this help make a scene easier to render?

I wonder if rays not hitting the objects or creating shadows helps to render faster because computer has less information to calculate? Should this be something to pay attention too when finishing a project? 🙂

I’m not sure. But that is an easy test to set up. Just render a scene, see how long it takes and how much memory it uses, then render it again but this time set up some light linking and shadow hacks and al that good stuff and see if something changes. My money is that it will actually take a bit longer to render if we do some light and shadow hacks, because probably it will have to go an extra step to achieve it instead of skipping a step. Come on Yevheniia, make me a winner.

Omar is right, using Light Linking and/or Shadow Linking will generally (always?) increase your Render times.

Damn, oh well 😀 Thanks for a fast reply.
