Hi Carlos,I am a student from Upenn and recently I started working on a game project that needs tornado effects. The main idea is using analog input to control how tornado moves so that the player can cause as much damage as he can. My team planned to work in Unity3D, but we don't know how to implement the tornado effects. If you can generously share the resources for creating that tornado (animations, particle effects, code, etc.) we would greatly appreciate it and give you appropriate credit when the game is done.If you are interested, I can let you see our high concept doc. Thanks a lot!
