Chaos Corona for 3ds Max > [Max] Daily Builds
The new Corona Converter feedback thread
brr:
Hello Corona Renderer team,
I would like to share some additional observations that I hadn't noticed before while using the Corona Converter in the simplest mode, "convert everything."
For points 1 and 2, I have uploaded an image. Please see it in the attachment to this post.
1. Sometimes it is necessary to convert materials while having the original scene materials side by side. To achieve this, I make copy of them in slate material editor and attempt to convert the copy using the last option, "selected material editor slot only." However, it turns out that this option is only working in the compact material editor. Why?
The compact material editor is very outdated and has many limitations. Most users haven't been using it for many years.
Unfortunately, there is currently no information available about this in the tooltip, so it took a considerable amount of time to discover the reason. It would be very helpful (and even logical) if this option also worked in the slate material editor.
2. In the converter, there is also an option to show or hide texture display in the viewport for selected objects. Unfortunately, this function rarely works in the converter, unlike its counterpart in 3ds Max itself, where you can globally make visible or hide textures in viewport.
3. While converting and checking scenes and objects, I also came across an important missing feature.
Since Corona is compatible with basic Vray materials, sometimes in a large Corona scene, a certain number of models with Vray shaders are lost. It would be very useful to have a "select objects without Corona shaders" function in Corona Converter. Perhaps there is currently a workaround for this? I would be grateful for any tipps.
Best Regards

WHEN WILL THE CONVERTER WORK PROPERLY???
It's broken and almost unusable for years.
I understand that it's not easy to handle old/wrong materials setup from many sources, but if you can't do anything, just bring back the legacy converter as an option because it used to work like a charm.
At least, please make the "force non-metal" option work as it should. The materials always be converted to metal even if it is selected.
Also, the "convert CoronaLegacyMtl" should be disabled by default. (who wants to convert CoronaLegacy if not necessary?)
It will ruin the scene that has a bunch of models with shit legacy material setup if you forget to check the convert selected objects only option.
OR change the convert selected objects only as a default.
OR just add an option to save settings
cheers,

In the mean time you can use the script I made that converts Autodesk Physical to Corona Physical in this post here:
https://forum.corona-renderer.com/index.php?topic=31214.msg214027#msg214027
Its fairly basic but covers Diffuse, Glossiness, Roughness, Normal, Metal, Non-Metal, Opacity at the moment.
Also I have a version I'm tinkering I can release this week that now changes the Advanced option to use Glossiness if using Glossiness workflow (instead of inverting the Roughness with a color correction node, I wasnt aware of this while making it). It also will support Displacement, IOR, Anistrophy, Emission/Self Illumination.
I just made it since I already have a few scripts I made that do similar things so figured it might help you out until the official release by the Corona team.

@James Vella, maybe it's worth creating new topic in the user contribution board? Especially if you have plans to continue development of the script. Honestly, judging by the amount of users requesting physical to Corona material conversion, i think your effort deserves a lot more attention than it got so far.

Sure if it helps. I didnt want to create a 3rd thread about it and bog down the forum but since you moderate this place I can do that if you think its best.

Not sure if I plan on developing it further but just wanted to help out for the time being and give myself a little project to work on. All the code is in .ms format so you can copy/paste, change, learn from it, whatever to suit your own workflow.
Also happy to hear some feedback about its real-world use since I'm just doing what I think would be useful but I dont actually ever use Autodesk Physical materials so I'm just pushing buttons =D
