Radiant Arcane Phantasm Mod adds legendary astronomical spells for Iron’s Spells ‘n Spellbooks with built-in real-time colored lighting and ray-traced shadows. This mod gives you powerful cosmic magic where each spell lights up surrounding blocks and casts soft shadows without needing shader packs. It also brings custom tooltip styles, floating combat damage numbers, and full compatibility with Iris and Oculus shaders.

Radiant Arcane Phantasm Mod

Features:

  • Astronomical Spells: Adds legendary magic inspired by real cosmic objects with unique avoidance mechanics.
  • Real-Time Point Lights: Spell effects cast bright colored light on nearby terrain based on each spell’s active phase.
  • Ray-Traced Shadows: Renders soft shadows using a 64x64x64 block volume around the player camera.
  • Light shines through fence gaps, iron bars, and open trapdoors to cast matching shadow patterns.
  • Uses temporal reprojection and spatial filtering for smooth, clean lighting output.
  • Features visual effects like screen-space gravitational lensing around black hole spells.
  • Offers seven tooltip visual styles that match the color theme of each spell.
  • Displays optional floating damage numbers above attacked targets with merged damage totals.
  • Works alongside Oculus and Iris shader packs without overwriting world rendering geometry.
  • Operates independently of vanilla block light levels so mob spawning rules stay untouched.

Commands:

  • /lightpollution frame <style>: changes the active tooltip frame style.
  • /lightpollution damage on: turns on floating combat damage numbers.

Configuration:

  • tooltipStyle: sets the default visual look for spell tooltips.
  • floatingDamage: toggles floating merged damage numbers above hit targets.

How to Use:

  1. Cast any legendary cosmic spell to see real-time colored light and soft shadows on nearby blocks.
  2. Type /lightpollution frame <style> in chat to switch between different tooltip panel designs.
  3. Type /lightpollution damage on in chat to view merged floating damage indicators over targets.
