Hi all Would be nice if the V-Ray scene converter can take into account the opacity of a standard material and bring that across into the refraction of the V-Ray material. For quick tests especially on imported scenes with millions of objects and materials, when you run the scene converter you don…

But why you need this transformation of the mapped opacity into a refractive shader ? The current conversion is Standard opacity > V-Ray opacity map. Which is the expected result I think.

Well I think the problem is that some people use opacity as a way of “simulating” glass. I think Morne received a model from a different software package/user. And they used opacity there to simulate glass. Morne can’t you use VMC or Zorb or something for a quick conversion after. And indeed opacity…

Our material converter doesn’t take into account opacity value under the Standard material. You may use the following converter instead - it does exactly what you like converts opacity value of Standard material to Reflection value in V-Ray material. http://www.scriptspot.com/3ds-max/scripts/vraym…

Thanks Svetlozar, I’ll give that script a try! (but I still think the native ChaosGroup one should have an option for this)

You can almost logically say if the Opacity Channel has a Map then it should transfer to an Opacity Map if not the opacity colour should transfer to refraction colour. Makes sense to me!

Better scene converter for opacity to refraction

Would you please explain me the logic why the Opacity Color of Standard Mtl should be transferred to Refraction Color of V-Ray Mtl instead of Opacity Color(VrayColor into Opacity slot)?
