This package includes:
Realistic textures and materials for traditional Japanese paper lampion lights.
Two models, a big one and small one, ready to use, as Prefabs.
A custom light flickering script so you can set up anything from static to casual to windy flickering, separately for each light. This can also be accessed from other scripts.
Extra textures so you can create your own logo / decal overlays on top of the lampions.
Since these lampions use the Standard Shader's emmision to glow, their light is also visible in your Global Illumination, and even in realtime, depending on your Reflection Probe settings.
