Custom Emissive Texture - GregTechCEu/GregTech GitHub Wiki

Developers and resource pack authors can easily have emissive textures and set bloom effects.

Emissive Texture

• For model-based blocks: Similar to CTM, you only need to set mcmeta file for the texture that you want to have the emissive effect.

{
    "ctm": {
        "ctm_version": 1,
        "gregtech": true,
        "extra": {
            "light": 15
        }
    }
}

light here represents the default level of light it emits (from 0~15). You can also set sky and block separately, as CTM does.

• For CEu machines: They are mostly overlay textures in assets/textures/blocks/machines and assets/textures/overlay/machines. You do not need to set the mcmeta file for them. Just add a new texture file for the emissive part named XXX_emissive.png.

Bloom

• For CEu machines: You don't need to modify anything; all emissive textures have the bloom effect by default.
• For model-based blocks: You just need to add an extra line to the mcmeta file: "layer": "BLOOM".

{
    "ctm": {
        "ctm_version": 1,
        "layer": "BLOOM",
        "gregtech": true,
        "extra": {
            "light": 15
        }
    }
}
