Item Glow adds true emissive rendering to items in Minecraft.
Any item that uses an _emissive texture variant will render at full brightness - glowing in your hand, in inventories, and anywhere items are rendered. No shaders. No OptiFine.
This is a lightweight, client-side mod designed to feel like a missing vanilla feature.
_emissive texturesSimply add an _emissive texture variant to your item model.
Item Glow handles the rest.
No configs required. No special APIs. Just works.
