VFX specialist who creates digital simulations of natural phenomena and physical dynamics – including water, fire, smoke, cloth, hair, destruction, and crowd behavior using specialized software to generate realistic motion and interaction that would be impossible or impractical to film.
What is a Simulation Artist?
A Simulation Artist is a VFX specialist who creates digital simulations of natural phenomena and physical processes. These artists use specialized software to generate realistic effects such as water, fire, destruction, or cloth dynamics.
