UDK is Unreal Engine 3 – the complete professional development framework. All the tools you need to create great games, advanced visualizations and detailed 3D simulations. The best tools in the industry are in your hands.
UDK comes equipped with a powerful material system, complete with a visual interface comparable to the non-real-time functionality provided by XSI and Maya, so you can create arbitrarily complex real-time shaders on the fly.
can u animate a texture?
Yes.
Rotate it, pan it or both! (At the same time if you're cool like that :D)
