We're going to set the Secondary Bounces…to none and we'll set the Primary Bounces to Light cache.…
Now, here is a render of the scene with no GI turned on.…Now ,let's take a look at a primary bounce of Light cache in the scene.…We can already see quite a bit of light filling in our box and our structure.…Now, Light Caches, pretty fast and gives you a good result with the primary bounce.…If you turn Light Cache on for the secondary bounce as well, and you render…the scene, you may be surprised to see that there is actually really no…difference between the two renders.
