create a menu to change texture on a certain object

Hi, im kinda new C#...

  1. im trying to create a custom gui menu where i could choose in a listbox where the list of textures i click & apply to the obj

  2. create a ease in/out popup with a hit of the spacebar.

thanks in advance

ps: tried finding tutorials on the net, but dont know how to modify from there..

You might want to have a look at the Character Customization example project. If you're still trying to figure out C# - you might rather want to start with something like C# Unity Tutorial.
