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.

Ray generation alone has a recursion depth of 0. If TraceRay hlsl function is invoked inside a closesthit shader for example, then max_recursion_depth must be at least 1. Executing more bounces than declared can cause the graphics device to go into removed state and can crash the application.
