In this recipe, we will optimize our scene as best as we can in order to decrease the total render time.
It is better to underline something from the beginning. As we said earlier in this book, rendering can be a quite long story. Rendering an animation is a much longer story. No matter how much we are going to optimize the scene, our rendering is quite heavy, and we have to render 375 frames. With that said, let's get started!
Optimizing the scene means we need to get rid of what is not strictly necessary in a certain moment. It will happen during our animation; something that is really close to the camera and needs a lot of detail in a certain moment will be far away and almost invisible later on. And when the thing is not so close to the camera, it is useless to have the maximum detail possible. We will start by optimizing the heaviest mesh, the Land mesh.
Let's optimize the Land mesh:
