I have a small army of zombies, with a sun lamp behind them. I set the sun from "No shadow" to "Ray shadow" and now the zombies have shadows. But the shadows are much too sharp. I changed the world settings to give indirect lighting, and gave it 3 bounces, but it didn't seem to affect it. Is there a way to make the shadows from the sun more blurred, less sharp?
Use the Lamp > Shadow > Soft Size setting. By default for a sun lamp, it is set to
0.1, which produces sharp shadows. Increasing that number will make the shadows cast by that lamp softer.
Note: in order for you to see the softer shadows in your render, you need to increase the Lamp > Shadow > Samples value to something higher than
Soft Size = 0.1
Soft Size = 5.0
