The open-source 3D graphics suite Blender now offers Cycles, a rendering engine that adds a new degree of realism and professionalism to your projects. In this course, George Maestri introduces Cycles, and reviews its lighting types, materials, and render settings. Learn how to layer shaders, enhance surfaces with texture and gloss, and add lifelike lighting and shadows to your scenes. In the final chapter, follow along with a small, self-contained project, where a simple architectural interior will be rendered.
At this point we have our scene pretty much ready to render. So let's go ahead and take a look what we have. And as you can see we've got a pretty good lighting model. So we can actually start doing our final render. Before we do our final render, one of the things we want to do is make sure we check our dimensions, which we set up at the beginning of this process. And let's also scroll down and check the Sampling. Now right now for our Render Sample we have this set at 200, which should give a good render, not perfect but pretty good.
And then also we are set up for full Global Illumination which should give us the best lighting model as well. Down here we have Performance. At this point I have this set for Auto- detect which will use all 12 of the Threads that I have on this particular computer. If we want we can change it to Fixed and just dial in the number of Threads we want. This will allow you some extra processing capacity to do other tasks while you render in the background.
I'm going to keep this on Auto-detect. So once you have all of that, you can start rendering by either doing Render Image or hitting the hotkey, which will be F12. And once we do that we can start rendering. And now we have our final render. With a quality of 200, you can see that there is still some speckly highlights in here which means that we really do need to up our quality before we do another final render.
So here under Samples, we really need to bring this up much above 200. Now for this particular scene, I find a value above 1000 is probably a good value to start with. Now this will increase your render time and depending upon your system this may take a little while to render. But remember that in order to get high-quality renders you do need to render a little bit more. As you can see the process of lighting and rendering a scene really is just a method of building up from your main light sources to your secondary light sources and then doing the final render.
