Help rendering particle like dielectric one

[sazatai]

I would like to make one drop having dielectric's looks.
I think 
-  setting "Obi Particle Renderer > Render" to activated
-  editing ParticleSharder.shader
could be what I would like to do, but have no idea of what to write in the shader.
Could you please advise me?

Why not using the built-in dielectric shader?
Or are you trying to write your own, that mimics the built-in on?
