Pigment eplosion Done with Blender Geometry nodes without particle simulation or smoke simulation, the entire animation is driven by a "clock" that cycle an attribute from 0 to 1 each two seconds. If you want only one explosion, edit the Clock node group.
Feel free to enjoy the setup for your project.
