Hi Everyone,
In this tutorial I will try to explain the process of rendering and postproduction. I have used here two programs 3Ds Max and After Effect. Some of you might ask ''Why After Effect and not Photoshop?'' The answer is simple. After Effect allows us to manipulate adjustments in real time, in any second we can go and change brightens, saturation, curve editing etc. When in Photoshop after we change something it's done. Ok, so lets maybe start talking about tutorial :)
This tutorial will show you studio set up in 3Ds Max and some tips and tricks in After Effect. It is a good thing to know something about Photography and composition.

On this screen you can see my studio lighting set up. Lights that I have used here are only Photometrical, all of them are set up in that same way, meaning Uniform Diffuse in Light Distribution(type) + plane as ''Emit light from (shape)''. During your test renders it is a good think to render some pictures from the other angel not only camera one. Simply to see how studio looks like and how lights are working. Many of you probably had a lot of problems with reflection in car paint. You probably saw end of your studio, or some corners or unwanted objects. You can fix this either by putting Fallof map (fresnel) in your reflection shader or by changing light strength or limiting them using Far Attenuation in light options. On the right side of screenshot you can see my expousure control set up. In this moment knowledge from photography is very helpful simply because in mr Photographic Exposure Control we have similar options to the one that we can find in DSLR and other photo camera.
The little image that you can see here is a screen of all my lights in scene. Basically, all necessary information you can see here.
Finally, the render:) As you can see it is quite different from the one that you could see on web. During rendering it is good idea to keep hot spot and dark spot even, not to bright not to dark just average.

Before I will move to post production it is worth mentioning that my final out put came up with Material ID pass. Every different materials on this car have their own material ID number, I did that because later on in postproduction I want to have full control over all the car parts and image. Thanks to that we can do an animation and keep great post produced look. :)
Moving on to post production. This part is very important because we have to get all the colour, saturation and brightness to the right level.

Image above is my Material ID pass. This pass will work as a mask. Each of the colours are representing different material. For example Black – Paint, Pink – Glass etc.
On this screen you can see my After Effect set up, as you can see it looks quite busy but believe me after you work with it and call every layer properly its piece of cake ;) All of the material have their mask and colour correction. I usually divide my work on three sections.
Stage 1 – In here I'm fixing shaders by using curves or hue&sat. There is no over painting or something like that.
Stage 2 – Bug fix, sometimes mask can cause some bugs or if we don't have masks. We can create them in AE using pen tool or by simply rendering it in max.
Stage 3 – Stylizing well, this is most pleasant part of work. When all of shaders are fixed its time to look at studio. In this part we need sometimes to work a little bit more on render. In this case I have created here few mask using peen, and then by blurring corners and adjusting contrast/curve/hue&sat I have finished studio.
I didn't show my post production settings for each of layers simply because if you all will ever do renders this way, it is all up to you how will it looks and my settings wont work in your renders. :)
