AT-AT texturing and compositing

I have been modeling an AT-AT from the Star Wars films, and i decided to texture it and render the final 3d model and composite the render into a background. The aim was to try and achieve as much realism as possible. You can see the final image above. I kept a log of the different segments that i had textured and iv decided to log them in this blog for people to see the process that was involved in producing the image above.

Early models of the AT-AT before texturing.

I started from the foot upwards, from research i noticed the At-At models seen in the film were very dirty and oily looking. So i decided my at-at would look quite run down and dirty.

To texture the base of the foot a took the Uv's from Maya and imported them into photoshop. I also added a bump map to the foot to provide extra detail.

The foot

I added more dirt to the underside of the ankle section in the 2nd picture, as this is where i thought the dirt would gather on a real at -at.

I then began to create the texture for the arch section joining the ankle with the foot.

Added rust to the ankle section

Upper leg section

Some more detail, i added a bump map to the inner circle section of the upper leg to show possible wear caused by the spinning element resting above.

To achieve the image above, I re-painted over a still I found from the film for the base of the background. Then using the different options in photoshop I altered the colour and look of the 3d AT-AT so it fitted better in the scene. I also blurred the feet quite a bit and added snowy winds to the areas around the feet. This helped a lot bedding the 3d model into the painted background. Adding a very pale white wind and mist to the body of the at-at and its surroundings also helped it sit in the scene.

I hope you like the final result
