Subject: Atmosphere Setup for Composting with Live Footage


Eagle66 ( ) posted Fri, 12 June 2009 at 4:03 AM · edited Sun, 02 February 2025 at 11:58 AM

Hey,
i need some help to setup an realistic atmosphere. There not so many people which use VUE for VFX Projects. All VUE Pictures in the Galleries are nice, but the most of them don't work for VFX.

Here is a Screenshot of a live HD-Footage. I need an other part made in VUE on the left site, so i need this atmosphere:

100% Ambient, 100% Cover, 1% soft shadow, Fog and Haze: 1% in Front and 90% at horizon, Sky-Color is about RGB 176, 180, 185.

Which Lightning model is the best for this?

A second problem is the Grass, all VUE Grass have no realistic look like this at foreground.

Is this possible in VUE (7.5 Inf.) Postwork and Colorcorrection etc. is okay, but it should work.

Thanks

Thanks 4 this hint.
I have bought the entire CD some month ago :rolleyes: This tutorials shows always the workflow, but not the way to get realistic Images as output.

I have spend many times, but i don't find out the right settings.

Realistic means for me: only i know what is LIVE footage and what is from VUE.

I need something like this quality:

Well its not really my area of expertise but don't film and TV productions that want to match real world lighting and rendered lighting use a Light Probe to create HDRI images to use to light their renders so the two match?

Try to copy youre scene as a reference and work from there:

I tried a quicky, it could use some finetuning in color of the light..  Is this the kind of thing you are looking for?

Hmm, very nice idea to rebuild my footage scene. My intention is at final to build burning cottages at the left site on the footage - the follow are just rendertests.

Your rebuild composition is perfect - but when you look at this picture does anyone identify this as realisitic picture? Why not?

This is exactly my problem, it is not the color of the light - it is the very fine unreal structure of the trees and grass and the painted look of the rock.

Take a look at this e-on spotlight picture from a VUE 6 project - this don't work with my shoot, but it is realistic!  Don't look at the hole terrain composition - the important think are the natural trees and rocks.

Here is another rendertest i working on:

So my problem is to get natural trees and rocks....

ps: HDRI images is IMHO not the solution, all i read is to render GR - radiosity rendering Light

Couple of things that ive noticed..

1 - the line of transition is too visible- this is a dealbreaker, instantly you know somethings wrong.

2- the clouds seem odd

3 - the scale ofthe castle is off - each of those windows is massively bigger than a tree

Looks pretty good though :)

I played with it for a few minutes, and came up with this:

I could have worked harder on blending the plants and blurring them slightly to fit with the surroundings, but I'm thinking the matte line is key. Once I adjusted it to more realistically fit the contour of the cliff, the image started looking better. The default weed clump does leave a lot to be desired, but with only slightly better tools than mine (this was done in Photoshop Elements, so I couldn't load a selection from an alpha channel), more could be done to fit it in.


Eagle66 ( ) posted Thu, 18 June 2009 at 10:43 AM

Okay, thanks all.

But my problem is not the size of the castle-windows or the blending,  this was just a fast mask in AfterEffects for testing. Also the castle is stupid - i write above: ...final to build burning cottages at the left site on the footage. All others are TESTS.

When you take a look at the picture of Cherryman - i get this results too. But this are not realistic.

Again: My problem is a describe above - how to get **natural Trees, Grass and Rocks.

What is the important settings and light for results like this VUE 6 example.**

Okay - i hope everyone see the difference

well to be honest... the trees are the only believable part of that image and the only part that makes sense.

youll also notice in that image you keep showing, NONE of the trees are NOT blurred.

I doubt anyone will be able to give you exact atmosphere details becuase it differs for each picture.  You will just have to play around until you get it how you like it.

Its also not really very practical to say, "hey, im doing a picture, its nothign like this one, but I want good atmospheric settings."

you asked "but when you look at this picture does anyone identify this as realisitic picture? Why not? "

We answered.

Your example returns a 400 error for me, so I can't even see what you're talking about.

you need to remove the mirror-eu from the url.

Thanks, Rich. Now I can see that it's only the same image as in the first post!

Eagle66, I guess I'm not understanding why you're not happy with the trees in your castle render. Other than the jpeg artifacting, the ones in front of the castle look realistic to me.

I don't  asked for a screenshot of the setup, my question was a general.

This picture (correct link here now) has a complete different and realistic look as i seen from VUE. All VUE-Tutorials on the web don't show such realistic pictures as result. You are also not able to get this results with post like photoshop, etc. The blur is because it is a screenshot from a movie sequence with active blur.

So i believe this quality is not possible with "normal VUE" or with "normal" Trees. I also believe this spotlight pictures from e-on are rendered in VUE xStream with mental ray oder RenderMan and NOT with the internal VUE-Render.
