Corona converter

Hi all,

I would like to convert standard material to corona material (in default setting), I have tried to convert by class - It seems like all link images are gone. Anyone have any suggestions ? There are a tone of materials in my scene. My fingers almost broken. Thank you !

Have you tried using Corona Converter?

Yes I have tired but all settings are not set in default setting. Please find the attached image.

I just tested converting some standard scanline material to corona physical mtl and they worked correctly using corona converter.

Maybe I don’t understand what exactly you are doing. What do you mean “default”?

Are you saying that when materials should be converted, they should have “default” corona values? They should not have values which were set in your standard scanline materials?

“Default” means (for me) when you create new corona material (first image). The problem is when I use corona converter, IOR and roughness are not set to “default preset”. I have to set one by one to be “default” Any possible ways to set all materials in default preset in one click ? Thanks for testing !


What is your standard material settings before converting them to Corona physical? By default legacy scanline materials comes with 0 specular level, which means no specular reflection, hence Corona materials are converted to replicate that - IOR set to 1.0

You can batch edit converted materials with this handy script: https://forum.corona-renderer.com/ Batch material edit

Oh thanks romullus and Nik. You really save my life and my fingers !

You can also try this script also to batch change corona physical material values of selected objects or entire scene.

Thank you ! Avi This is very helpful script.

I received a feedback from CharlyRT to add “Mask propagation” options to the script I shared earliar. It was half finished so I finished the whole script. Find it attached below this post. Hope it helps.

Thanks Avi
I totally forgot to mention that if is it possible to add Corona Legacy too, I tried in a scene from work and most assets uses Corona Legacy and for some reason many has Mask propagation set to “Always”. I have a script that could do that, but now that Corona team is writing a proper one that could be useful.

I have added support for Corona Legacy also.

PS: Always save your scene and take backup before using the script.
