The material allows you to change the surface material depending on the type of incoming beam.
Choice Strategy
Selects how to determine the beam type.
- Use first event. The type of the beam is determined at the first collision and does not change afterwards.
- Use actual event. The beam type depends on the current collision.
- Use single event or default. The material will be selected if the beam has not changed its type, otherwise the Default material will be selected.
For example, after the first reflection event, Reflection will be selected. After the second reflection event, Reflection will be selected again. And if the second collision is a refraction, Default will be selected.
Default
The material is selected for a beam type that does not fit into any strategy.
