FsDynamicLight

Every light in this mod is controlled by resource packs — item and entity light levels live in plain JSON files under assets/fsdynamiclight/, and pressing F3+T applies your changes instantly, no restart needed.

In short: held items, dropped items and burning mobs cast smooth, naturally fading dynamic light at good performance — and you decide exactly what glows.

Dynamic Light Sources

1. Block-Based Light (Automatic)

Any item that is a placeable block with a static default light level automatically emits that light while held, worn or dropped — no configuration needed. The actual vanilla values are measured at runtime from the block's default state (26.2):

Dynamic-light blocks whose default state is unreliable (e.g. redstone lamp, copper bulb, candle) are excluded here — set them in the config if you want them lit.

2. Custom Item Light (Config)

Items with no default block light but a clear glowing look (or blocks you want to override):

3. Entity Light (Config)

Entities have no default light — every glowing entity is defined here:

4. Runtime Behaviors

Configuration

Both configs are plain JSON inside a resource pack. Place your pack's files at:

• assets/fsdynamiclight/item_light/light_levels.json — item light
• assets/fsdynamiclight/entity_light/light_levels.json — entity light

Changes apply on resource reload — press F3+T with no restart needed.

Format

{
  "15": ["minecraft:glowstone", "minecraft:lantern"],
  "12": ["minecraft:blaze_rod", "minecraft:lava_bucket"],
  "8":  ["minecraft:glow_ink_sac"],
  "0":  ["minecraft:torch"]
}

Notes:

• Invalid light levels and unknown IDs are skipped with a warning in the log.
• Config overrides the automatic block light: setting an item to "0" (or any value) takes precedence over its block default, so you can darken or brighten any block item.
• Items that are placeable blocks with a static default light do not need to be listed at all — they already glow.
