This is a Spinasaurus, I created using Auto Desk Mud Box. I started be using a T-Rex model in Mud Box and then modified it using the sculpting tools in MudBox. The Character is based on The Jurassic Park movie dinosaurs.
Step 1: Modifying.
Using the sculpting, paint and texture tools. I modified the T-Rex in various way to come up with my version of a Jurassic Park Spinosaurus. I'm just learning how to use MudBox.
