This Muzzle Flash was aimed to be efficient using fake lights and RGB-packed textures. I referenced projects such as Overwatch and Valorant, and inspected how they implemented their effects. I used a cross-plane mesh with Vertex Color to create cleaner opacity and reduce and flipbook with color parameters that have high values on the textures.
