Rainmaker is a simple but very useful mod that adds one 1 block. The rainmaker.
The rainmaker is a simple block where its only purpose is make it rain. The mod is super lightweight and runs fine on almost all computers. With a jar size of about 10KB and optimized code.
This mod was made specifically for Jadedcat's Agrarian Skies 2. The mod is highly configurable for mapmakers. It also fits well into modpacks and regular survival.
The mod comes with a fancy looking 3D trapezoid shaped block rendered using GL11 and tessellation. There is also a really cool looking thunder storm animation plus water spewing up in the atmosphere when placed before the rain kicks in.
