thanks david for sendin on the link. actually i did have a look already at the 3d models on turosquid. i really like this 3d model, http://www.turbosquid.com/3d-models/3ds-bottlenose-tursiops-dolphin/227727
but it is not rigged and is a bit expensive at $160, but realistic and v close to what i want to achieve. the fact that it is not rigged and expensive are the reason for putting me off. do you know other sites like turbosquid that might offer such 3d models?
