I made these tornado effects using the HDRP Unlit Shader Graph in Unity 2019.2.0b1. The cylinder mesh was created in Maya LT then modified in Shader Graph to give each tornado its own effects like fire, ice, and wind. These were fun to create in Unity for others to use in their own projects. Thank you for watching!
