Now duplicate that sphere (Ctrl+c, Ctrl+v). Name one sphere GI, and the Other one Visible. As the names suggest, one of the spheres will be visible when we render and the other one will be for GI (GI stands for Global Illumination). Create the materials needed for the lightĬreate a new Material. Turn off all of the channels except Luminance. After that, go to luminance, and apply your con.hdr as the texture. As you can see, it’s a bit bright, so we are going to tone it down a bit. We can do this by setting the Brightness to 0%, and set the Mix to 50%. Now duplicate this material, and name the duplicate GI. The only change we are going to make to this one is setting the MIP Blur Offset in the Luminance Channel, to 10%. By doing this, it evens out the light, so when its rendered it will not look as blotchy. Now, apply the GI material to the GI sphere, and the Visible material to the Visible Sphere. Now we will have to change some settings for our spheres. Make sure only the following are checked: So right click on the Visible Sphere in the Object browser, and go to Cinema 4D tags > Compositing. Seen by Camera, Seen by Rays, Seen by Transparency and finally Seen by Reflection. Once that’s done, also add a Compositing tag to the GI sphere, and make sure only the “Seen by GI” is checked. ![]() Now, after all of that complicated work, your Object Browser should look like this. ![]() Our scene is finished now, now we only need to set the correct rendering settings. If you tried to render it now, well it would look like a normal every day render. But that’s not what we want, we are going for Photorealism. So for that we are going to need some Global Illumination. OR you could use these: Open up the Render Settings, and go to the Global Illumination tab (Note: On the older versions of Cinema 4D it was called Radiosity) and turn it on. Now, you could spend a half hour messing with the settings, tweaking them to get them just right. Once that’s all sorted out, click on Options, and make sure you turn off Auto Light. If you don?t, your scene will looked all messed up.Īnd now for the usual end stuff.
