Scruff/Behind the Scenes

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

In 2010, Scruff made her debut in the fourteenth series.

In his introduction Scruff was voiced by Matt Wilkinson in the UK, and Kerry Shale in the US.

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 series 14. 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.
