It seems some users have this issue with Corona 12 Update 2 https://forum.corona-renderer.com/ Corona 12 Update 2 Vantage Live Link Try to roll back to Update 1 - Vantage live link should work there.

This is logged for our developers as (Report ID=CMAX-1630).

Is this still happening with Corona 12 Update 2 Hotfix 1 and Vantage 2 8.1?

Hi Maru
Its happening even with Update 2 Hotfix 1 and latest vantage

Hi,

Is this still happening with Corona 13 and Vantage 3? If so, can someone confirm?

Not sure if it’s the same. I just installed vantage 3.02 and using the 22aug corona 14 daily. First time I’m trying to use vantage and I can’t get it to export the animation from my scene properly. Is it a requirement that I do “step1” with the live link and scrub the timeline, like in the article here: https://support.chaos.com/hc/en-us/articles/36239447702801-How-to-Render-Corona-for-3ds-Max-Animations-in-Vantage ?
My scene is a mess and usually crashes if I scrub it with everything visible. So i’ve jumped to step 2 and just directly click the export animation to vantage button. It takes a while, but eventually gets it loaded up in vantage. Here I just get a default camera (none of the other cameras in the scene is there??), the default camera matches that of my active camera I had when exporting.

But, when I click the “play” button, vantage just crashes and and says it’s saved something in %TEMP%, thought when I go there, I can’t see crash report.

If I click ctrl+R instead and try to render the animation, I cannot select the “sequence” tab. It’s just grayed out. So it’s like no animation was exported.

The animation works fine when rendering locally, via Pulze’s renderflow app and also on garagefarm.net.

I really miss some good documentation from Corona on how this workflow should be set up re animations.

When I move around manually in the scene in vantage, some objects are not rendered correctly (like asphalt made with a blend material) and the standard animated escalators from Railclone doesn’t show up at all.

This is a bug. We have it reported as (Report ID=CMAX-1935). The animation export randomly doesn’t work. The solution is to downgrade to Vantage 2.8.1.
Normally, when you are exporting an animation, Vantage should display options to render the animation.

Thank you for the quick reply Maru, I will give 2.8.1 a try right away! Is there something regarding railclone animated objects I should also know about or can you link to an article/docs?

They should work fine. We are aware of some Forest/RailClone problems when using Corona Preview (daily) builds, but it should be ok in 13 HF2.

Can confirm the export animation button and sequence works with vantage 2.8.1, so that’s nice. What’s not nice is that the exposure is way off and I can’t seem to adjust it in vantage and then have access to the sequence option again. With the “export to animation” we can’t adjust anything in vantage really and if I click away the render dialog and do adjustments, sequence is grayed out again. I can use auto exposure, but the whole idea of setting up the animation in max is for maximum amount of control :smiley:

re: Railcone: Turning off the “use instancing engine” under display mode in the RC object made it show the geometry in vantage, and a quick render test seems that the animation of the escalator works, so that’s nice :smiley:
Wish I could zoom around in vantage and click “play animation” to have animated stuff move, but nothing happens when I click “play”. Guess this only works with live link and the scrubbing the timeline (though in such a huge scene I have, that doesn’t really work as there’s a 10-30sec delay every time 1 frame changes in vantage).

Blend material is having a hard time in vantage too. It’s basic pavement or asphalt in slot 1 blend mat. Then a water type material in slot 2 and a bitmap as a mask (to have a wetness/puddles). Its like it only reads the water material slot and surface becomes ultra reflective.

I can’t seem to get materials with opacity to work either. Even just super simple without bitmap or anything in the opacity slot. Just changing the color from black to white. Nothing happens.

Rendering out the sequence with default HQ settings, only the very first frame got denoising applied to it?

Sorry for the long write and maybe not correct place for feedback, but now I got going :wink:

Overall I think it looks super promising. Renders out full hd that with denoise looks fairly okay in just 1-2mins on my old 3080 card. Compared to around 5mins on the 3990x cpu.

If all of the above was fixed/worked, I think this could almost save us from using a render farm gettings this 3000frame animation out and just do it locally. Could pay for new better GPU and still save money doing it this way.

Hi Jens,

Thank you for taking the time to write such detailed feedback.
I went through each point and tested internally. Below are some clarifications:

  1. Exposure mismatch during animation export
    In my investigation, the exposure looks correct.
    However, please note that any post-production adjustments done inside Vantage are not applied during animation export. This is expected behaviour at the moment.

  2. Sequence export becomes grayed out after adjustments
    Yes, this is expected currently. The UI becomes locked once certain changes are made.

If you would like this behaviour improved, please log a feature request here:

Choose “Add a new idea” and describe the workflow you would like to see.

More information:

  1. No adjustments possible during “Export to Animation”
    This is also expected at the moment. Scene controls are intentionally locked during animation export.
    If you need a more interactive workflow, please feel free to submit a feature request on the Ideas Portal.

  2. Play Animation button not working
    Animation playback must be controlled from the 3ds Max timeline.
    Vantage syncs animation directly from Max, so please use the play button or timeline inside Max instead.

  3. Animation playback via Live Link only
    Yes, this is expected behaviour at this time.
    If you need direct playback inside Vantage, please submit this as a feature request.

  4. Slow timeline scrubbing in heavy scenes
    This is a known issue and already logged internally:

(Report ID=CMAX-2097)

  1. RailClone geometry not visible
    I was unable to reproduce this issue on my side. RailClone exported correctly via Live Link in my tests.

  2. RailClone animation preview
    I also could not reproduce this.
    Animation updates correctly when scrubbing the timeline in 3ds Max. Please make sure playback is driven from Max rather than Vantage.

  3. Blend / layered material issue
    Unable to reproduce on my side.
    I tested using Corona Layered Material, and it rendered correctly in Vantage.

  4. Opacity not working
    This one is already logged internally for our developers:

(Report ID=CMAX-2209)

  1. Denoising only applied to first frame
    Can you please try this again with new version of Vantage? I was unable to repro this on my end.

  2. Export workflow resets after dialog changes
    This is related to the current export workflow and UI locking behaviour, same as points above. Feature requests are welcome if you would like this improved.
