Sorry if this has been asked before, i've read through most of the post here and didn't see this question.
Anyway's the problem im having is from the visible light created by povray tutorial on this site, when render it shows the light from the directional light source but doesn't iluminate the particles is all povray will render, just curious if anyone know if this is a povray setting problem. Cause honestly povray is a bit confusing to me. I have followed the rest of the tutorial turning the black particle setting to grey and still no show in the particles. Thanks for any reply.

There are a lot of "details" required to make this work properly. I would suggest reading the tutorial on the subject very carefully. If you do anything wrong you won't get visible particles.

Yup your right i missed the simple part of not casting shadows on the point lights in the scene. Thanks
