3dsMax Corona > Vantage - Feedback & Various Incompatibilities

Hi Avi and team- can I please check, is it really necessary for us to post one-by-one each max/corona feature that we’re discovering isn’t compatible with Vantage? I’ve found several today having tested it for the first time, but posting each of those separately feels unintuitive to say the least. Is there a better way? I’d imagine/expect Chaos to be aware of the various max/Corona features that aren’t currently supported by Vantage as it’s very obvious when you fire up any test scenes. For example:

  • composite material (max) - just displays black
  • maps driving IOR e.g. fresnel maps, but literally any map in the IOR slot breaks the material
  • colourcorrect (max or corona) doesn’t quite work the same, but does function
  • running an environment map (e.g. coronasky) through a colourcorrect - doesn’t work at all, displays black
  • it won’t read your AGX/tone mapping by default but you can easily load it in manually into vantage
  • I don’t think SliceMtl is currently supported

Vantage is REALLY impressive having briefly tested it (max 2026, corona 14, vantage 3.0.3), and the link (live or otherwise) with Corona is looking super promising, so I’m keen to get these features working so we have 1:1 parity with corona within 3ds max as soon as possible, as it will make all the difference to pipelines/feasibility.

In an ideal world we could keep a thread like this open to general bug-hunting/incompatibilities with Corona and users could update it as we go, instead of a piece-by-piece report system (as much as I know you guys love to track that stuff).

Cheers,

Hi Alex, I don’t see any problem with posting like this, as long as all issues are related to Vantage.

We will check your reports and make sure they are logged in our systems.

You can also check this page showing Corona for 3ds Max + Vantage compatibility: Corona for 3ds Max Features

Please note that it hasn’t been updated to reflect Corona 14 changes yet.

Thanks for the update, Marcin. We’ll be doing more testing as time goes on and will update this thread if we find anything new.

My best,

Another small bit of feedback:

  • Some kind of real progress bar/percentage/objects-remaining for Export Scene > Vantage would be super handy. At the moment the Export just sits there and gives you a time spent value which isn’t all that helpful.

Cheers,

Here they are:

  • composite material
    – works in vray
    – logged as CMAX-2126

  • any map in the IOR slot breaks the material
    – this should be already fixed - please let us know if there are still some cases where it fails

  • max or corona color correct
    – Corona Color Correct works pretty well; Max Color Correction so-so
    – logged as CMAX-2127

  • feed corona sky through Max/Corona color correct = black
    – logged as CMAX-2128

  • Slicer Mtl
    – currently not supported, the V-Ray Clipper object works
    – logged as CMAX-1812

  • progress bar for export
    – logged as CMAX-2129

Regarding this one:

Can you clarify? Do you mean pretty much “Vantage should use the same tone mapping as Corona”? Or is this about some specific operator like LUT?

Thanks for the updates and logging!

Yes, basically. I would hope for a 1:1 experience going from Corona in max > Vantage, so that means whether you have 1 or more LUTS loaded into your camera/global stack. In our case we use AGX so that requires (currently) 2 x LUTS to work. But only 1 of them can be used at a time in Vantage. I would ideally also propose that any custom LUTS being used in Corona are automatically saved and loaded into Vantage. At the moment I believe they need to be manually added to Vantage first, but I might be wrong on that.

Cheers,

I don’t know if full 1:1 tone mapping experience would be possible, but we can start with LUTs. Reported as CMAX-2130.

Sounds good! Thanks a lot. Another one I can’t remember if I mentioned:

  • Sometimes coronacamera clipping appears not to be quite the same in Vantage and you need to clip further

I couldn’t reproduce the camera clipping issue. If you have a scene (preferably simple) where this can be replicated, please contact us.
It may be related to the tilt correction not working as expected with Vantage, which we have logged as (Report ID=CMAX-1719).

Hey guys,

I see a new version of Vantage is out. Is there a simple changelog or perhaps a list of any of our flagged issues that have been fixed? Would be great to know what’s left on the list.

Another one we need to test properly but I believe is not yet compatible is refractive caustics, is that right? Wondering if the new “fast caustics” Vray feature might make it to Vantage (and Corona!) any time soon?

Cheers!

Hi, you can check vantage changelogs inside the application directly. Please see the screenshot attached.

You can also find it here: Release Notes for Chaos Vantage 3

I will also look into this to check if/which of the issues were fixed.

“Wondering if the new “fast caustics” V-ray feature might make it to Vantage (and Corona!) any time soon?”

Not soon, sorry. Earliest that this could possibly be will be Corona 16 which is set for November-ish, but planning for 16 hasn’t started so that might change (unfortunately if it changed it would most likely mean Corona 17).

PS we have yet to take a look at how this works in V-Ray to see if it is possible / practical in Corona, too.

Thanks, all. Will check more on Vantage’s changelogs.

A little sad to hear fast caustics will be so far down the road, at best, in Corona, considering what an obvious win it will be for everyone. No chance of bringing it into 15 as an optional experimental feature through the dev mode perhaps?

No sorry, everything already chock-a-block in terms of what we have to work on with no time for any other development :frowning: 15 is a little over a month away at present.

Also bear in mind fast caustics have the tradeoff of not being “realistic caustics” - they are a fake / cheat :smiley: So not sure how useful that is for Corona users overall where realism usually takes priority :wink: But you tell us! Especially if anyone gives it a go in V-Ray to see how well it matches your needs.

I can count on one hand fingers how many times i have used caustics in Corona. There were many more times when i wanted to add caustics to my scene, but quickly dismissed the idea, because how difficult is to set-up them and how much render times balloons. I would take fake but fast caustics any day of the week, just bring em up.

Unfortunately, none of the things listed in this thread have been fixed/implemented/improved.

The things that have been fixed internally or are scheduled to be fixed soon-ish are:

  • Vantage animation render does not start until 3ds Max timeline slider is moved (Report ID=CMAX-2120)
  • Slowdown when rendering high-poly objects in Vantage (Report ID=CMAX-2097)
  • Moving the camera inside 3ds Max while using Vantage live link resets any changes made to environment in Vantage (Report ID=CMAX-1622)
  • Forest Color map not rendering in Vantage (Report ID=CMAX-2219)

—Internal note—
Collective tasks:
(Report ID=CMAX-2135)
(Report ID=CMAX-2138)

That is unfortunate indeed. Even more sad on the development of the issues I flagged, considering they’re from 4-5 x months ago, and moreso if they’re not on any kind of next-up roadmap. I would regard that kind of compatibility as a top priority for parity, otherwise it’s just more barriers to entry for Vantage.

On caustics - we use them almost every single day in various projects. There would be a huge, huge benefit to being able to use these looser/approximated “fast caustics” for a lot of real use cases. Especially for stills where ultimate realism is more flexible as you can fix stuff in post if necessary.

I just would expect that any new Vray features like that which the community get rightly excited about would automatically be pushed as a priority into Corona since surely the bulk of the work is already done? As an experimental feature, sure, as I mentioned. Reality is that our ability to use DBs in production is more or less zero at this stage, we rely on final builds, so if we’re locked out of something great like that for many months that’s a shame.

It’s worth noting that, so far, it looks like Chaos are the slowest partners to get max 2027 support going. Is there a plan to bring out a hotfix for Corona 14 to allow for 2027 support?

Yes, we already have an internal release candidate and want to release ASAP.

Great to hear, thank you.
