Texturing - Normal and Specular maps

Here is the normal map I created for the tracks. Below are the low poly track I baked the texture too and the high poly track design I baked from.

Here is the first version of the specular map I will use on the digger.

UV Mapping

Here is the final UV layout for my digger, set out with as little dead texture space as possible.

 

Below are a few shots of the digger with a UV spacing texture, showing that there is little to no stretching on the model.

Digger Model

Here is the basic process I used to create my digger.

 I began by setting up image planes of the front, back and side views.

 I then made a simple block out of the larger components of my digger.

 The first section I added detail to was the cab and the rear section.

 I then added detail to the arm sections, the joint and the base. The final bit i made was the undercarriage.

Here is my almost finished model.

CGM More Reference

Here are a few more images of the digger I will model. These just show more detail of certain parts which should make them slightly easier to model.

CGM Reference Images

 These are the front, back and side views of the construction vehicle which I plan on modelling for this module. This post also contains a side and front on view of just the digger arm.
I took these pictures at JCB Harrison which is a JCB dealer located on the Whisby industrial estate in Lincoln. This particular digger is a JCB 8018 CTS.
