Thanks Adrian, although I'm still not sure which smoothing tolerance would be correct for plugins or other applications and I cannot identify this as a plugin bug today because it's a core smoothing tolerance limitation when rendering dielectrics. So, I guess it's user's responsibility to maintain correct smoothing angle limit for the object. There are different host applications having different smoothing limits by default.
