Hey Odforce! I just published a new course - Pyro II - Flames & Sparse Pyro. This course aims to uncover the main ideas behind the new sparse pyro solver by making a realistic fire simulation.
If you've already bought the old version of Pyro II, then you'll automatically get this course for free! Check it out at https://www.cgforge.com/course?courseid=pyroii-sparse
Cheers!
