I would like to create a texture map for a 3D car model I have. I am not sure where to start. I thought maybe I could unwrap the 3D object to a 2D image and then use this as an outline to draw my texture. Is this possible, or is there a simpler solution?

Thank you in advance!

What you are asking about is called UV mapping.

"UV mapping is the 3D modeling process of projecting a 2D image to a 3D model's surface for texture mapping."

Source: https://en.wikipedia.org/wiki/UV_mapping

UV mapping is normally done when creating the model in 3d modelling software, although there may be assets in Unity able to do the same. To my knowledge Unity is not able to directly UV map.

You can however, change the texture of an object inside Unity as well as assign objects various colours and materials.

To my knowledge you need 3d modelling software to do so, but yes, it is possible.

You can try to change it through scripting, but I'd recommend looking into 3d modelling software instead as I believe that if it is possible it will be bothersome.

3D modelling software I know of:

  • Blender - Free

  • Maya - Licensed

  • 3DS Max - Licensed

    Thank you for the swift reply. I see what I have to do now based on your links. I need to add 'seams' to the object, so that it can be folded. I think this is a bit above my skill level as the object is quite complex. – Razor Robotics Mar 26 '18 at 15:43
