Guys, do I need to have vray installed to open and convert the models (evermotion librarys) to corona?

Yep, but even the demo will suffice.

Hello, and thanks for the wonderful conversion tool.

I did a straight conversion from a V-ray file to Corona using your utility and did a straight render.

As you can see, there are two glaring differences. First, the semi-transparent curtains in the background aren't rendering properly.

Second, the ceiling lights are not cascading onto the walls, and materials like the satin bed cover are not reflecting (gleaming?) the shimmer of the light.

Can you suggest changes I need to make to these after conversion that will bring the image closer to the V-Ray render?

Thanks, and what a great tool.

Sorry for the late reply.
Can't say what is happening with the curtains (and the lamp shades in the middle) without having the scene but the ceiling lights and some other ones look simply too dark too me. Turning up the intensities should probably be good enough.
If you can send me the curtains and/or lampshade material (with the original vray shaders!) I can have a look and see if I can improve the conversion :)
Any sufficiently advanced bug is indistinguishable from a feature.

Iray material: I've written a conversion for iray to corona, and integrated it in Martin's script. I've emailed Martin the script so he can integrate it in the official release.

Tried to convert my old Mental Ray scene to Corona and got following error message:

Get it here: http://www.racoon-artworks.de/CoronaConverter/CoronaConverter.html

changelog:
v1.30 - [2016/10/27]
  • added unofficial conversion of (downloadable) iray_material by Michiel Quist, 3diee.nl
  • fixed MR Reflective_Occlusion map conversion

Thanks goes to Michiel Quist for the iray_Material conversion! (I haven't tested it though).
@ler01: Unfortunately I cannot track which in which slot the map is used atm - so this is not possible right now, sorry.
@romullus: Fixed :)
I've also updated the maxscript documentation

Thank you! I still have lots of MR scenes, so this fix will be handy indeed.

Btw, I made a Corona 1.4 to 1.5 PBR converter (supporting glossiness maps and values), in case someone missed it

Fantastic! Is the Iray Material compatible with this operation?

Thanks,

Is there a way to use CoronaConverter (Vray Material -> Corona Material) without the use and installation of VrayPlugin. There are a lot of Models out there with VrayMaterial assigned.
It would be nice to implement that in the next version of the script.

thx for help!

No. You'll need to have Vray installed to convert Vray materials. BUT it does work with the free Vray demo installed - even after it has expired.

Hope it helps
