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,

As noted in my post that you quoted ;) "Please say which version of Max, which version of Corona, and which assets (you can post their name)" - it would also be good to see some screenshots showing what you mean, in particular along with info on lighting and tone mapping in case either of those are playing a part. Thanks!

as I said, I don't use the Cosmos, just tested them after I saw this thread. Random picked 10 people, and 8 of them are incorrect. I just posted here to confirm that they look wrong. I can't tell you all of their names because It may use the whole day or a couple of days to list their names. (I can do it but you have to hire me :P)

If I were you, I will let someone in the team dig into them, set up the scene, and test "ALL" the assets (especially the People asset) one by one to see if they're wrong and fix them.

You guys are much more clever than me. Perhaps you have a better solution.

I attached some random picks. I didn't try to pick only the bad ones. Completely random. What do you think?

Because of different workflows between users. Let's say I'm following a strict PBR workflow, and you're not. Who's scene will they work perfectly in? Because one of us will have to tweak them? My workflow would require all albedo textures to be within a certain sRGB range, whereas values as low as 0,0,0 and 255,255,255 might be acceptable for your workflow? Who's workflow should the creator prepare the models for? And that's just highlighting 2 different workflows, I'm sure there are many other factors at play. I might prefer to use Physical Shaders, you might prefer to use Legacy shaders? Who knows

I think you missed the point dude.

Are you trying to say because we have many workflows, then the assets shouldn't be correct on any workflow even on the PBR workflow?

PBR is Corona's standard, almost everyone uses it, so make it correctly on PBR.
If anyone uses Alien workflows, let them fix themself because they're not the standard.

I dont think this is a very good example to be honest. If the assets work well in Vray it should work in Corona. If they are setup for PBR or Legacy it doesn't matter - there should be parity. It is time consuming sure, but its not difficult. I think this is the point here, the items in cosmos should import in correct from the get-go, if you want to adjust things to fit your particular workflow or 'standard' srgb ranges then that's up to you at that point, but the base asset should be plug and play.

Totally agreed with James. Your explanation is way better.
I believe everyone uses the Cosmos because they'd like to save time. Imagine that if they have to fix iOR / albedo / Roughness on 80 of 100 assets, It's pain.
The concept of Cosmos is drag and drop and it works perfectly. So make it be, that's it.

Aren't a lot of these problems the same as assets bought/downloaded from anywhere else?

They're not necessarily setup correctly for your individual workflow. Everyone has different workflows right, the model creators will make the assets to suit their own workflow. If the two don't align then there will be issues no doubt.

9 times out 10, assets need tweaking.

I notice it more and more these days (not necessarily in this thread), but people expecting minimum input for maximum output. I get that time is money and all that, but sometimes you actually need to do a bit of work yourselves.

Most of the adjustments are simple tweaks too, but it's too easy to blame the creators rather than do the simple fix yourself.

I personally don't use Cosmos because most of them suck.

The point is that Cosmos promotes itself as "high-quality models, materials and HDRI skies that work perfectly with your visualization projects."
So it should be ready to use, shouldn't it?
and the most important thing is it's made by the renderer's company not random download from the internet. It should work perfectly with their renderer, shouldn't it?

If they're simple tweaks, why don't they do it and make it ready to use as advertised rather than blame the users and let them do the fix themself?

Please say which version of Max, which version of Corona, and which assets (you can post their name). Looks like a known issue where the IOR is too high, making them shiny, temporarily you can manually reduce the IOR after import.

(Internal ID=902432258)

Most of Cosmos's people assets; IOR Incorrect, Skin too dark and redish.
Check them out

TBH, I use this feature in every scene.
Besides bringing it back, it would be best if you named it. It's not a "legacy", it's the main feature!

Please bring back the old converter (convert to Legacy Material) as an option.

I've been fighting for this unsuccessfully during v7 dailies. But you can do it manually:
get a Corona v6 installer
use the "unpack files" option and extract the files somewhere
go to "Autodesk\3ds Max [xxxx]>\scripts\CoronaRenderer (the Max version does not matter, it's the same script for all)
copy "coronaConverter_v1.45.ms" to <3ds Max directory>\scripts\CoronaRenderer\

You can start it manually from there, or use the attached button/script for convenience. Result: if you press the converter button of the official toolbar, you get the current converter. If you press the button of the script, you launch the old one. You can have both side by side.

Good Luck

Edit: attention, this is not a supported scenario. It is not assured that the old converter will work in future Corona versions. And it should be considered as a temporary workaround anyway.

Thank you Frood, for the solution and the fighting :D
It works perfectly.

I hope this will be reconsidered.

Please bring back the old converter (convert to Legacy Material) as an option.

10-20% of converted materials are completely wrong, especially metal and liquid material.
It's not fun to fix a hundred materials.

You can work on the new one and make it better. But we just need a lifesaver button for now.

You can make it smaller than VFB size by increasing the image upscaling factor.

[Max] Resolved Bugs / [Max 2020 + Corona 4] Physical Cam bug (Freeze)

« on: 2019-07-31, 15:41:38 »

I don't use Physical cam anymore, but I have a problem when open old scenes that use it.
I can't open or merge those old files. After a few hours, I figured out that the problem is Physical cam + Auto Vertical Tilt Correction + CoronaCameraMod on top.

You can re-produce by creating a Physical cam > Enable Auto Vertical Tilt Correction > Add CoronaCameraMod on top.

I don't have any problem with max2018. So, I'm not sure if the problem is from Max or Corona side.

**Corona4 hotfix1
