IRender Soft Shadows
Soft Shadows is a feature of IRender which re-samples the sun and lamps to create soft shadows.
Larger lamp bulbs will create software shadows - see the examples below.
- The shadows are softened with each rendering pass, so you need to allow enough rendering passes to see the soft shadows.
- The wall on the left has Auto Bump enabled.
Another Shadow Example
Here is another example using a 0.05" lamp on the left and a 2" lamp on the right.
Soft Sun Shadows
There are several things which effect the softness of shadows from the sun.
If the Sky is turned on, or turned on for illumination even when off, then light from the sky will soften the shadows from the sun.
Even with no sky, the Cloudiness Setting will make the shadows software by adding a cloudy effect.
