You need to convert Vray proxies to Corona ones first. Try this script: https://forum.corona-renderer.com/index.php/topic,3247.0.html

Thank you it worked .
But as you can see the textures are a bit weird. I did the material convert.





The great thing is that with all those polys the corona in 2 hours was faster than vray in 2 hour was still in prepass.

It's a "little" too small to say something about the materials. All I can say is that Corona handles opacity differently than Vray or MentalRay. Corona uses the rgb channels, not the alpha of an image. That can be problematic if the original materials were using (for example) and png with embedded alpha. In cases when "Mono channel output: Alpha" is set, Corona would still use the rgb channels and this cannot be converted properly.
But apart from that there is still the possibility that the conversion sucks ;) If you could elaborate what didn't convert properly or let me have a look at the original material I could say more to that and probably fix some issues.

Hello

You guys are great in fast feedback!

Now that's strange. I fear I can't say anything to that without having a look at the material. Doesn't look like an alpha issue to me, probably too much translucency but who knows =/ . Would it be possible to send me just the one material that is going from green to brown? I don't need any objects, just the material and the maps for debugging.

Hello

Ok! You can go to : https://www.dropbox.com/sh/vlvo0jqudrmdb4i/AABPNPxsZeATaruMjGWll1m4a?dl=0
And there are -mat file and the textures so you can see if you can debbug .

Also put image from vray full render just for compair.

Hope you can find a solution, hehehe!:p

Thanks for the material! I did a conversion here and it seems to be perfectly fine. So I guess this was some bug in one of the old script versions that is already fixed :)

You will need Corona 1.0 or the latest daily builds for it ;)

[miragemig]

ok
i downloaded the last version of corona  and it is not working....
I was only testing.  where can i get 1.0 version? it is  realeased yet?
so there is no way i can check if the conversion is done properly?
