Textures

Glow Layers

Including a glow layer for an entity variant is as simple as adding a single texture file. Add a texture file with the parts you want to glow to the same directory as the texture the layer is for with the filename of <baseTextureName>_glow.png and the system will use that as a glow layer for any mobs using the <baseTextureName>.png file as its texture.

For example, if you have a texture skeleton.png in the directory assets/jsonentitymodels/textures/entity/minecraft/skeleton/adult/skeleton and you want to add a glow layer to it, you simply add a skeleton_glow.png file to the same directory.

Iron Golem Cracks

Similar to Glow Layers, the cracks on Iron Golems as they are damaged can be added as simply as adding a few extra textures. There are 3 layers to "crackiness": Low, Medium, and High. Each one should have a texture in the same directory as the Iron Golem texture it is for with the filename of <baseTextureName>_crackiness_(high|medium|low).png. Again, (high|medium|low) indicates that there are 3 files, one with each of those words filling that space (e.g. <baseTextureName>_crackiness_high.png).
