Test these settings with another trial rendering. Your room should now look like Figure 5.20.
Figure 5.20: Rendering with fuzzy shadows
At this point, you have set up a quite usable rendering, and it is time to do a final rendering.
Start a new rendering and select “08. PhotonMap—Fine + AA 0.3” as the setting. When it
finishes, notice that the blurry shadows look much better than they did using the trial settings.
Furthermore, you most likely noticed that it took much longer to create the better-quality rendering.
To familiarize yourself with the various rendering methods that Kerkythea offers, try rendering
the same scene with these settings:

02. Ray Tracing—High + AA 0.3—This setting does not calculate indirect light and
considers only the direct sun- and spotlight for illuminating the scene.
08. PhotonMap—Fine + AA 0.3—PhotonMap is the technique that we have used for
this tutorial so far. This method calculates indirect light and fuzzy shadows well.
02. Metropolis Light Transport (BPT)—This method is unbiased, which means that it
uses real light properties and does not just approximate them. You will see that indirect
light and some materials look much better using this method—especially in complex
scenes. Stop the rendering process when you are happy with the result.
22. Clay Render (PhotonMap—Medium)—This rendering method ignores materials
and applies a default white material to all surfaces.
Path Tracing—This is an alternative method used mainly for exterior scenes. It doesn’t
work well in our case.
Once you have created the final rendering, keep the Rendered Image window open and
adjust the Tone Map settings to your liking. Then click on Save and save the rendered image
as a JPG, PNG, BMP, GIF, or HDR file.
