Transparent refraction without reflection in Iray

aaráribel caađo

I can't figure out how to decouple refraction from the reflection model. I want to create a shader that only refracts light—no diffuse, no shadow, no reflection, nothing but bending the light. This isn't a common phenomenon, but also doe exist in reality where heat bends light. I want to make a magical effect, so I'm indifferent to physically plausibility :p

Is it possible to just refract within Iray? The ultimate magic effect shader would have some reflection at a high incident angle (>80º or so) to give it a hint of shape beyond the refraction.

Or is there a Shader Builder-like thing I could use to make a shader with?

Hi,

with iRay you can build the reflection alone with glossyness. So just set glossyness and glossy layered weight to 0. This should do.
Don't know what influence has glossy refelctivity, if present. But that depends on a different setting of scattering.
