Corona to Vantage animation exposure issue

[Benjamin_A]

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.
