Houdini 19.5 smoke simulation. Credits to John Kunz, "Tire Burn", the Indian VFX school tutorials, "Pyro Smoke Simulation Course" and Sadjad Rabiee. This project took me a while to complete...over a month. It was easy to get the smoke effect but it was tricky to make the smoke behave realistically there is still room for improvement but I am happy with the results so far.
