With my question I want to know if DESIGN 2D/3D skills are necessary in order to create a game using some engine like UDK or Unity.
I have experience as a developer, and experience with openGL, I have also some experience with 3dMax, but Im NOT able to design something from scracth. I simply dont have the skills.
In this kind of engines, is there a way to create and customize levels or characters for example?
Thinking in something related, I will think in the character editor of games like World of Warcraft, etc. I would like to know if the creation of levels and characters would be like that.
