particle visible in reflection
This post helps a lot on the 'particles cannot be visible in reflection' problem. The way to solve this problem is kinda tricky!
So the main point is that only particle which can be rendered with Maya Software can be visible in reflection and refraction. So when the particle type with s/w checked, the 'visible in reflection' and 'visible in refraction' boxs are checkable. Then after check them, change the particle type back to the one we want.
