Alpha specular refraction

[joonaskaustel]

Hey guys

Does anyone know how to solve these darkened edges between the cap and liquid in specular material with alpha? Or whats the optimal technique to deal with alpha and specular? Using environment?

Hi joonaskaustel,
are you using PT or PMC kernel?
Other kernels are not the best with glass/liquid.
You can use the Visible Environment option to have different backplate/reflections/refractions from the Primary Environment node.
