V-Ray Scene Converter - Support Standard Mtl Extended Parameters Advanced Transparency

[Morne]

Hi Team

Currently the scene converter totally ignores this section of the standard material. The tick "Convert Standard material opacity to V-Ray material refraction" makes no difference. In paticular the Amount spinner (Amt). I think it would be enough to just map the Amt Spinner (from 0 to 100), to a the VRay Material Refraction color slot. IE 0 = 0,0,0 and 100 = 255,255,255

So with the standard material, the opacity spinner and the amount spinner is reversed. 100 Opacity means no transparancy, however Amt set to 100 means 100% trancparency. I think the Converter should take both into account and do a conditional check to see which one makes the material more transparent, and work out the equivalent V-Ray refraction based on that.

Also, the material editor also ignores the Amount spinner and show the material as opaque, when in fact it has transparency

Cool? Thanks Guys!

Will see what can be done about it - thanks for the pointer. Out of curiosity, what kind of materials are you trying to convert?

Best regards,

These are just standard materials generated. In paticular, glass from the new 2020.2 sketchup importer. It now stick the transparency where I mentioned, instead of opacity like it use to with the old importer. Would be good to get thos as quick as possibly into vray without manual work
