Diorama Blockout

To fit along with the vehicle, we were given the task of creating a suitable scene for it to be placed within. This along with the vehicle will later be placed in UDK and rendered both in a playable minimum 30FPS scene and screenshots for composition.

For my scene, I used the location where I originally took the images of the vehicle for reference and changed a few areas.

Here's the original location:

It's a relatively simple scene with a warehouse and containers. Here is the blockout render.

I added a ramp for interest to the scene and put smaller details on the warehouse such as CCTV, Alarms and Lights above the door.

Texturing

After the UVs have been mapped, I can export them as a UV Snapshot and open them in Photoshop. This gives me an outline of all the pieces so I can texture the model effectively.

To begin with, I paint a diffuse layer. This contains all the base colours for the model before overlaying images or adding texture to it.

The next map I created was the AO (Ambient Occlusion). This simulates where light will hit the model and creates a map allowing for shadows and highlights to show through. Below is the AO by itself and when added to the Diffuse with a base metal texture applied.

 After the AO, I wanted to create detail for bolts and screws without adding them by using geometry. This was achieved through the use of a normal map. This map manipulates the light to make it seem as if the texture was being raised or lowered in places where the geometry is actually flat. Below is the normal map.

The final model (minus decals) is shown below with a default Lambert material assigned.

UV Mapping

Now that the model is complete, I now move on to the Texturing stages. The first step is to UV Map the model so the texture applies correctly.

I select the faces I want to UV and use the Planar Projection in the axis they are facing, this gives me a UV layout that fits the outline of the geometry. This can then be scaled and placed on the UV Texture Space along with the other UVs ready for texturing.

Below is a snapshot of the UV layout and applied texture for reference.
