Realistic atmosphere render

[mister3d]

You can render fog in max, or make it in post like after effects using z-depth channel, which is a mask for the effect. If you want something like clouds which look good, you will need a plugin like afterburn if I'm not mistaken. Max natively cannot create anything of a good quality with native tools out-of-the-box afaik.

Was thinking of using Z-depth myself. But just don't think i can get that photo look by using z-depth. The reason why i think 3D don't look like a photo is just because it's to clean, to nice looking, you need that grainy feel to it.

but thanks :D

You can't get that photo-look either by using z-depth or using a cool plugin. This all needs good textures, shaders, lighting and compositing. It's better if you show the pic so people could suggest you how to improve.

Here's the photo and my pic.

That's the photo http://globalcc.files.wordpress.com/2009/07/virginatlantic787ii2.jpg

And my render is attached. and in there you can see that the photo is more grainy because of the atmosphere. don't worry about the background. in the final movie there is not going to be a background

This image is a jpeg. so pretty bad quality

The most striking thing is you need to map and texture the specularity shader, as now it looks too procedural and uniform. But looks good for the time being.

Haven't really made a specular map yet. but i'm about to. That model is an old one. That's why some of the Flaps are missing. and there's only one light in the scene at the moment.

So the atmospheric thing i'm talking about. is that just making some blur or something inside Photoshope or aftereffects?? yet so you don't have all those clean lines, perhaps just some motion blur?

I've got what you mean, it's blurring of edges of cg objects usually, there's a more correct term in compositing, but usually you make this procedure when integrating if you don't have enough fresnel reflection falloff.

Thanks alot! I think i understood the last part :P but thanks

Maybe it's called "edgeblur" or something. In your render you have composed the plane over the sky photo. To do it correctly, you must render them separately, then compose in a compositing software, color correct each element (adjust them so they match), and edgeblur the plane. Usually this edgeblur includes a bit or a "color bleeding", i.e. adding the color of the element under composed object, in this instance it's the blue of the sky.

[Korfits]

Thanks!! that made more sense in my ears:D i'll try the edge blur out as soon as possible. It sounds like a nice thing to do. thanks a lot

I don't see any sky color on your plane in the render. There should be reflections of the sky, and sky-colored ambient light at least.

[Korfits]

the reason why you don't see any reflections is because i'm not done with the lighting:P
