Flamin’ Horse

This texture pack transforms the skeleton horse into a horse on fire, surrounded by animated flames and glowing emissive textures.
The pack adds dynamic fire effects that react beautifully in dark environments, giving the mob an intense and infernal look worthy of the Nether.

It requires Custom Entity Models (CEM) to work properly — either through a compatible version of Optifine, or using the ETF (Entity Texture Features) and EMF (Entity Model Features) mods.
It works on Minecraft versions higher and lower than 1.21.
