Summary:
Environmental Rads is a NuclearCraft addon that adds configurable per-dimension passive radiation from the environment.
Currently for Underhaul only.
Features:
• Configurable per-dimension passive radiation from the environment. • Configurable simulation of the absorption of environmental radiation by blocks with respect to their hardness. • Configurable simulation of atmospheric absorption of radiation with configurable start and end heights, allowing for the realistic tapering of radiation received.
Usage ideas:
• Use in conjunction with a space exploration mod such as Galacticraft or Advanced Rocketry to improve realism and motivate the construction of shielded extraplanetary bases.
• Add to a custom map or alongside a mod that alters biome spawning to create a highly irradiated surface wasteland.
• Make skybases and high-altitude living more hazardous.
Future Plans:
• Permit radiation level update cycles to differ in length and rate from the configured NuclearCraft radiation updates. • Add some way to extract energy from this radiation. • Cause high levels of environmental radiation to damage and degrade the world. • Add configurable per-block radiation absorption overrides. • Delay initial onset of radiation, per-player or globally, to create a grace period for players to prepare to burrow. • Allow for the creation of radiation "cycles" - i.e. a certain number of days at a certain radiation level, another number of days at a different rad level, etc, on repeat. • Radstorms similar to those from Fallout 4, where you must take shelter or be irradiated. (Suggested by [wiktorco](https://www.curseforge.com/members/wiktorco)) • Compatibility with Advanced Rocketry atmospheric density. • Optional radiation spillover from adjacent blocks on the x and z axes to make walls more important. • Optional radiation checks from every world axis, not just from the sky (Very much a maybe, could be prohibitively performance-heavy).
• Per-biome rad level config (Suggested by [Nyoobster](https://www.curseforge.com/members/nyoobster))
