Immersive realms (realistic)

This modpack contains 70 mods and has just been released; please let us know if you encounter any bugs. It runs well on mid-range and high-end PCs but won't work on very weak ones (it ran fine on my mid-range PC, which uses integrated graphics). The modpack adds multiplayer voice chat, a cold/temperature system, and makes nights and caves much darker; it also features shaders, dynamic lighting, and other elements you'll discover while playing. The mod was created by a Brazilian developer.
