This piece is my entry into learning the Houdini for games. The smoke simulation was cached, rendered and exported into a looping 64 frame (2k) sprite sheet animation, using one RBGA texture. Rubble was generated in Houdini using a Sphere and Voroni Fracture node to create interesting looking rubble chunks. I created a quick hand-painted blast mask in Photoshop and a crack pattern in Substance Designer, and then the rest was composed in Unreal with the help of the BlackBody node to achieve that hot glow look!
