3dsMax Livelink - Material - issue: refrection-transparency "jumps" on 25/26

[david_buerger]

Hi, i hav e the issue where i want a certain transparency, but refraction 25 is too less (like nothing) and 26 is too much. why is there such a big jump?
its just a plane with a simple vray Material. is there a workaround?
see images attached, thanks!

Hi david_buerger,

This is a known behavior - it is an optimization on our side and we will revisit it. From the screenshot I see that you are trying to fake a translucency with refracton and refraction glossiness, which we do not support currently. I would suggest trying to achieve the look with a 2sided material. Can you please try it and report back?

Best regards,
Alexander

Initially when we developed Vantage, we found out that people like to put a very low refraction value in their leaf materials.
Since leaf geometry is very dense, this affects performance a lot.
So we disabled refraction below a certain threshold.
