Fireworks are awesome, that's why I've made this resource pack which includes all you need to make great scenery designs and fireworks effects to give your sky a fantastic look.
20 fireworks + 1 variation of each one (PNG)
6 fireworks groups (PNG)
6 trails + 1 variation of each one (PNG)
8 simple trails (PNG)
Includes fireworks, trails, all particles, materials and 4 premade camera angles to make variations. Distributed over different collections for an easy management.
NOTE: This is not an addon, so you don't need to install anything. Bloom effect is made on Eevee (no post-process needed)
