Abstract: With natural disasters or man-made disasters occurring frequently, a lot of game designers hope in the design of virtual disaster scenes to increase people’s consciousness of disaster prevention and self and mutual rescue. The requirements to produce the disaster scene are put forward, to improve the immersion feeling of the game players. This paper implements the strong assembly functions of mainstream Unreal 3 engine visualization of Unreal Development Kit (UDK) to show the disaster scene, and realizes the production of volcanic eruption, lava flow and thick smoke effect.

Key words: unreal 3 engine, disaster scene, unreal development kit(UDK)
