Method

RT Mirror Reflection is the fastest raytracing reflections node with only a single, sharp ray traced bounce supported.
This can be used to simulate mirrors, reflections and specular on any raytracing enabled specular material/surface. Rough reflections are not supported by this node.

As it only uses one bounce, secondary bounces such as a mirror reflecting another mirror will not work. This node is best-used for scenes that need to run more optimally at higher framerates.
