The idea for this project was born while watching the movie The Golden Compass, which has scenes on ice and snow that are really fantastic. I added to that the fact that I like old airplanes and then started to develop the idea.
Following that I began to work on the creation and composition of materials to be used in the scene. Even though this is a stage that is performed further into the process, I decided to bring this to the beginning of the process, because the main focus of this work was actually the materials.
The composition of the base materials (we will call base materials the materials that receive a layer of snow) with the snow material was made using the shader “Blend” and to mix the two materials the map “Falloff” as a mask, using a world Z technique.
The terrain modeling was made inside 3ds Max using simple resources, such as the modifier “Noise” and the modifier “Displace”.
For the modeling of the airplane I utilized the “Box Modeling” technique using as reference images found on the internet.
The mapping was made on 3ds Max using the “Unwrap” with the “Pelt Map” tool to open the mesh. However, using only the “Pelt Map” the result will not be good, so to correct the mesh after it is open I use the “Relax” tool, which can be found in the “Tools” menu. The option that presents the best result is the “Relax by Face Angles”.
The texture was all made in photoshop, using the painting techniques and the assembling of photographic textures.
With the airplane and the scene ready, it is time to put the two together, and for that I had to wreck the airplane. I opted to do that manually, separating the elements, mashing and tearing the bodywork.
The lighting of the scene should be pale and diffuse, because the intention for the scene was to picture a blizzard during the day, therefore it should not be dark.
When it was all ready I Just had to wait a few hours for the render to be completed, so that the post production adjustments and corrections could be performed.
The post production work was divided between After Effects and Photoshop. The first corrections were made in photoshop and consisted in removing and fixing minor imperfections. For these corrections I used the tools “Healing” and “Clone Stamp”.
The second stage made in photoshop was to perform the “Matte Painting” to compose the background of the scene.
With the corrections and the “Matte Painting” ready I took the material to the After Effects to begin the assembly of the elements. The first stage is to compose the render with “Matte Painting”.
To better integrate the scene I created a fog effect using the filter “Fractal Noise” of “After FX” and a render pass of Zdepth as a mask to give depth to the effect.
After adding the fog to the scene I used three more Adjustment Layer with filters of Brightness & Contrast, Levels, Shadow/Highlight and Hue/Saturation to correct and adjust the scene and only after that I added the layer with the snow.
With that I finished the AfterFX stage rendering what was done so far and taking it once again to photoshop, because I felt the need to make further adjustments on the scene, as the frosted metal parts of the airplane, to compose a render pass of Ambient Occlusion and also to make a new adjustment to the background of the scene, giving it a little more contrast and turning the tone to a lighter blue.
The next stage was to select all the layers and converting into “Smart Object” to continue the adjustments that are now to simulate the effect of a 35mm film. In order to do that I used the filter “Lens Correction” to create an effect of chromatic aberration, increased the sharpness of the image with the filter “Sharpen” and applied GRÃO with the filter “Add Noise”.
Now comes the final stage, where once again I applied a series of filters intending to soften the edges of the image but maintaining the sharpness and the correct level of grain.
I would like to thank all of my friends for the help and I hope that you all have enjoyed this material.
