Hi, I donít have the crash without the intersection; the photons simulation on the lens works well.

I try the intersection between a box and a tube, for example, and I have no problem. The problem exists when I use the Fresnel Lens; I obtain the following error:

Program received signal SIGSEGV, Segmentation fault.
