public float maxRecursionDepth;

Description

The maximum number of ray bounces this shader can trace (Read Only).

This value can be set in a .raytrace file using #pragma max_recursion_depth followed by a positive number.

If you set max_recursion_depth value too low, your graphics device may go into removed state, and crash Unity. To generate rays, your max_recursion_depth value must be at least 0. However, if you invoke the TraceRay HLSL function inside a closest hit shader (for example) your max_recursion_depth value must be at least 1.
