Hi
I have a material test scene for V-Ray and Corona where I have applied a shell modifer to simulate inner thickness into a sphere with a simple glass material.
As you can see in the attached images Corona has a very thin inner amount and V-Ray has a thicker result, I have tried changing the max ray depth in both engines and activate “Reflect on back side” in V-Ray material but, still Im getting the same ressult.
If I increase the inner amount in Corona, I need to change the volumetric scattering distance but theres no thickness.
Yesterday I was asking in Corona forum how could I achieve the same ressult as V-Ray but I was told that the ressult from V-Ray is incorrect since V-ray material is set to ignore total internal reflection, I think he meant about the “reflect on back side” option, sincerly I like more the V-Ray ressult, but, if this is a wrong representation I think that the engine needs to improve this kind of situation, but if not, I would like to know which is incorrect or how to achieve similar ressults.
Hi
In Corona forum a developer helped me to get the same ressult in V-Ray as Corona, but its configuration was not practical at all, the original intention was simply turning off the hdr background by setting it as invisible, since in Corona you dont need a dome, you need to set up environment and to get the same effect in Corona the glass material showed like the example. Im intrigue now in which of the ressults is the physically correct. Im attaching a simple file as Corona, Vray and the one that was shared in the corona forum.

As Aram said, both are physically correct; the different engines have different setups, that’s all.
Thanks Hermit
