Hi,
nice video tutorial for 3ds Max about modelling Iron Man helmet. Something from the description:
In this tutorial i will show you how to model Iron Man helmet, texture it and render using Autodesk 3ds max and Adobe Photoshop. By this we will use poly modelling technique where we start from a single poly. This technique is widely used for car or head modelling and the steps and technique covered in this tutorial is the same and you can use them to model anything. We will start preparing our scene for modelling and place the reference pictures inside 3ds max environment. Because we are modelling from a single poly we need at least three pictures; front, side and back to be able to model the helmet according the reference picture.
