This Full HD video tutorial shows how to control reflection.
It should be useful for professionals as well as beginners in LightWave.
It’s sending ray (using ray-tracing Ray Cast node) in predicted reflection direction (using TrueArt’s Node Library Tools Reflection Direction node) to find out distance from spot to the closest geometry (if any).Ray-tracing functions are returning -1.0 if there is no geometry, otherwise returning distance. You can calculate position that has been hit by using equation world position = ray origin + ray direction * distance. If you will connect distance to Gradient you can control in what range reflection will be visible. Objects outside range won’t be reflected.
This tutorial is using TrueArt’s Node Library from
