IRender Soft Shadows
Soft Shadows is a feature of IRender which re-samples the sun and lamps to create soft shadows.
Contents |
Lamp Size
Larger lamp bulbs will create software shadows - see the examples below.
Small lamp placed in front of chair. 30 rendering passes. Note harsher shadows
Large lamp placed in front of chair. 30 rendering passes. Note soft shadows
Notes
- 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 Example
Here is another example using a 0.05" lamp on the left and a 2" lamp on the right.
