Corona to Vantage animation exposure issue

Hi All

I posted this to the Chaos Vantage forum and they mentioned I should post on the Corona forum as well. Hopefully this is the correct place.

Copy of my original post:

I have an animation in Corona which I would like to render in Vantage. I’m finding that I have no way of controlling the exposure of the animation at all. I open my scene in Vantage via Live Link and its over exposed (needs to be -5 on corona camera simple exposure). I know I can control it in Vantage, but when I come to render it via ‘Vantage Anim. export’ button it opens in Vantage over exposed with the render dialogue box open and if I close it to change the exposure settings and open it again I can’t render an animation as ‘sequence’ is greyed out. Is lowering the lighting settings the only work around or am I missing something? Any help is much appreciated, it’s entirely possible I’m missing something obvious.

Can anyone either corroborate that this is the case or suggest any other work arounds. I’m just about to test using the auto exposure tick box in the render dialogue pop up in vantage.

Couple of extra bits, I’m using 3DS max, Corona 13, Corona camera. I’m saying when I change any of the corona camera exposure setting (either simple of photographic) it seems to have no effect in Vantage.

Thanks in advanced.

Hi Benjamin,

We already have this behavior reported to the dev team as (Report ID=CMAX-1758). I am currently not aware of any workaround, sorry. I will look into it some more and let you know if I find anything useful.

I believe this should work, did for me.

In Max with your scene set up and ready to go, start Live Link. Adjust the exposure.

In Max, stop Live Link.

Now use Vantage Anim. Export, set your animation parameters in the Vantage dialog, and it should render with the exposure you set through the Live Link.

Let me know if that works for you.

PS - once the animation had completed rendering, Vantage itself went back to displaying the “too bright” exposure, but all the animation frames were saved with the adjusted correct Vantage exposure.

Thanks for the replies.

I did try TomG’s suggestion but this didn’t seem to work for me. The file I’m trying to use is 7.5GB so its extremely slow to setup the live link (although it does work). I’m hoping next week I’ll have a bit more time to test this with a simpler scene to be sure then I’ll feedback.

Thanks again

This and a lot more problems is why i think vantage for corona should have a discount for the users who are beta testing the software.

Definitely not a solution, but hopefully a workaround: you can enable “auto-exposure” in the Vantage Render Setup window when using the “Vantage anim export” option.

Hi Tom,

I’ve tried your workaround but it doesn’t work to me.
In general, when the Live Link Animation mode is active, there is no way to adjust the Vantage’s Post Production / Color Correction options at all.
I’ve tried everything and I found no solution. I would like to animate lighting and Camera movements effects made in 3ds Max but this is useless.

Hope you guys have a workaround soon.

Thanks,

I’ve found a temporary solution!!!

  1. Link the scene as Tom suggested
  2. Do all the Post Production / Color Correction work
  3. Stop the Link
  4. In Vantage under the Edit menu press the Save Scene Settings as Default
  5. Now activate in 3ds Max The Vantage Anim. Export and VOILA! It works at least like this.

The Vantage team should correct this, as it’s a big limitation. Would be nice to Save / Load those settings in a different file in this case and load it separately when is needed.

Thanks,

Dionysios -

Thank you, this is exactly what I was looking for.

My pleasure, I am glad it works for you as well.
Hope to get from the dev team a more logical solution soon.

Dionysios -

Hi,

just wanted to let you know that this issue still persists for me. Would be great if you could come up with a solution for this. Fast fix would be to add an exposure setting into the render dialog in vantage? So we can adjust the exposure when using the “Vantage Anim. Export” button?

Best regards,

Denis
