Scruff/Behind the Scenes

Background Information
Scruff is a fictional standard gauge tank locomotive created by Sharon Miller and Jo Jordan.

Scruff first appeared in the fourteenth series episode Thomas and Scruff, which first aired in 2010. His last appearance was in the twenty-second series episode The Case of the Puzzling Parts, which was released in 2019.

Since his introduction Scruff has been voiced by Matt Wilkinson in the British English dub, and Kerry Shale in the American English dub.

CGI Model
In 2009, the series introduced Computer-Generated Imagery (CGI) as a replacement for the show's long-standing live-action models. In 2010, Scruff was modelled in full CGI by Nitrogen Studios for production of the fourteenth series. The model was "hand-sculpted" in Maya, a 3D animation and modelling software.

According to Greg Tiernan, the CGI models are subjected to many rounds of review before they are submitted to HiT Entertainment for final input and approval.

Scruff has had modifications throughout the CGI series. These include:
 * Series 17:
 * He gains a rear coupling hook.
 * Series 20:
 * He gains a front and rear tail lamp.
 * He gains front and rear brake pipes and brake pipe outlets.

Texture variants
In addition to his standard livery, several other texture variants exist of Scruff's CGI model. These texture variants include:
