ALLEYWAY EXPLOSION FX

I kitbashed a street environment using free KitBash3D and Megascans assets, placing buildings, adding props, and procedurally scattering different assets. Once that was done, I moved on to creating the multiple explosive debris simulations. I utilized the RBD Bullet Solver to simulate the oil barrels using soft constraints, the Vellum Solver to simulate the exploding cloth pieces, and the POP Solver to simulate the rock debris. For the main explosion FX, I first prepped all of my colliders and created my initial sources using the pyro burst source node. I then used a Vellum grains simulation, which I trailed and rasterized, and also added a few extra sources to match the reference explosion's behavior. I adjusted and animated the different sources and fields, and once I was happy with the result, I moved on to creating both the sparks simulation and another smoke simulation for the drain smoke. In Solaris, I created my initial lighting setup using multiple light sources and a few instancers to copy lights to the street and building lights geometries. Finally, I split my scene into render passes and assigned AOVs for compositing.
