Emissive Textures add a second texture on top of a block which will render with no darkness and will be unaffected by lightmaps.

Important

They do not change the actual lighting around them. This does not affect actual lighting, just the pixel's brightness.

It is possible to add overlays to block textures, which will always rendered with full brightness. This can simulate light emitting parts of the textures.

The emissive overlays have the same name as the base texture + custom suffix. For example:

  • bedrock.png: base texture

  • bedrock_e.png: emissive overlay

The emissive overlays are rendered in the same block layer as the base texture, except overlays for textures from layer SOLID, which are rendered as CUTOUT_MIPPED. The overlays can also be used for items, mobs and block entities.
