Can someone recommend a course that shows how to combine an explosion with RBD destruction, like a building wall being blown out by a fiery explosion? I am wondering how to combine the two. Is this just done in the compositing stage, or can the fractured pieces interact with the fireball in a sim?
You can use particles advected by volume, or use vel of volume to apply force to rbd object. In both methods, use of SOP Solver is essential. The example below is in the lecture, Udemy - Master Houdini FX- Create Stunning Visual Effects rigs.
