Join Donovan Keith for an in-depth discussion in this video Lighting with Quasi Monte Carlo global illumination, part of Production Rendering Techniques in Cinema 4D.
Different methods of global illumination are better suited to different tasks.…QMC or Quasi-Monte Carlo is a brute force method that gives highly accurate, albeit often grainy results.…Let's go ahead and take a render of this scene before we add in global illumination.…I am just hitting Command+R on my keyboard, or Ctrl+R on a PC.…What we see is that we have a yellow sunlight as well as some blue light being contributed…by our sky and all this is coming from our physical sky.…I've activated a couple of special options on that sky, and you can piece through the…scene file if you want to examine those.…
To turn on Global Illumination, go into your Render settings and go to the Effect tab, and choose Global Illumination.…Now by default, if you go to the General tab you'll see the G.I. mode…is set to IR (Still Image). This is the GI mode we are going to use for most things.…But for our purposes right now, I want you to choose QMC for Quasi-Monte Carlo, go ahead and press Render.…You'll probably notice a few things, one, we now have shadows long shadows that are…
