Radiant Arcane Phantasm FAQ
10 questions players actually ask, answered.
How do I cast the astronomical spells?
The spells are part of Iron's Spells 'n Spellbooks, so you need to obtain spell books or scrolls through that mod's progression system first. Once you have a legendary cosmic spell equipped, cast it normally and you'll see the colored lighting and shadow effects activate around you.
Do the spell lights affect where mobs spawn?
No, the mod operates independently of vanilla block light levels, so the colored lighting from spells won't prevent mobs from spawning in dark areas. Mob spawning rules remain completely untouched by the real-time lighting effects.
What's the difference between the tooltip styles?
The mod offers seven different visual frame designs for spell tooltips, each matching the color theme of its corresponding spell. Use `/lightpollution frame ` to cycle through them and find the one you prefer.
Can I use this mod with shader packs?
Yes, the mod is fully compatible with Iris and Oculus shader packs and won't overwrite your world rendering geometry. The real-time lighting and shadows work alongside shaders without conflicts.
How do I turn on floating damage numbers?
Type `/lightpollution damage on` in chat to enable floating combat damage indicators. The numbers will appear above targets you hit and merge multiple damage hits into a single total.
What does 'ray-traced shadows' mean in this mod?
The mod renders soft shadows using a 64x64x64 block volume around your camera, and light realistically shines through gaps in fences, iron bars, and open trapdoors to cast matching shadow patterns. This creates natural-looking shadows without requiring a full shader pack.
Do I need to install anything else for the lighting to work?
No, the real-time colored lighting and ray-traced shadows work built-in without shader packs. However, you do need Iron's Spells 'n Spellbooks installed to cast the astronomical spells themselves.
What's the gravitational lensing effect I see with black hole spells?
Black hole spells include a screen-space gravitational lensing visual effect that distorts the surrounding landscape, creating a warping effect around the spell. This is a visual-only effect and doesn't affect gameplay mechanics.
Can I change the tooltip style permanently or only temporarily?
You can set a default tooltip style in the mod's configuration file using the `tooltipStyle` setting, or change it temporarily in-game with `/lightpollution frame `. The command change lasts until you switch it again or restart.
Do the spell lights affect performance compared to shader packs?
The mod is designed to be lightweight and works independently of shaders, but the exact performance impact depends on your hardware and how many spell effects are active at once. The ray-traced shadows use temporal reprojection and spatial filtering to keep output smooth.
