Armor Layer

ItemArmorGeoLayer has built-in functionality for allowing your models to have emissive/glow textures. This is similar functionality to that of the vanilla Spider eyes, which glow in the dark.

How to setup

Simply register the layer following How to add GeoRenderLayers setup like so:

public class ExampleRenderer extends GeoEntityRenderer<ExampleEntity> {
	public ExampleRenderer(EntityRendererProvider.Context context) {
		super(context, new ExampleModel());
		// Add the armor layer
		addRenderLayer(new ItemArmorGeoLayer<>(this) {
			@Nullable
			@Override
			protected ItemStack getArmorItemForBone(GeoBone bone, DynamicExampleEntity animatable) {
				// Return the items relevant to the bones being rendered for additional rendering
				return switch (bone.getName()) {
					case "left_boot_bone", "right_boot_bone" -> this.bootsStack;
					case "left_armor_leg_bone", "right_armor_leg_bone" -> this.leggingsStack;
					case "chestplate_bone", "right_sleeve_bone", "left_sleeve_bone" -> this.chestplateStack;
					case "helmet_bone" -> this.helmetStack;
					default -> null;
				};
			}
			
			@Nonnull
			@Override
			protected EquipmentSlot getEquipmentSlotForBone(GeoBone bone, ItemStack stack, DynamicExampleEntity animatable) {
				return switch (bone.getName()) {
					case "left_boot_bone", RIGHT_BOOT -> EquipmentSlot.FEET;
					case "left_armor_leg_bone", "right_armor_leg_bone" -> EquipmentSlot.LEGS;
					case "right_sleeve_bone" -> !animatable.isLeftHanded() ? EquipmentSlot.MAINHAND : EquipmentSlot.OFFHAND;
					case "left_sleeve_bone" -> animatable.isLeftHanded() ? EquipmentSlot.OFFHAND : EquipmentSlot.MAINHAND;
					case "chestplate_bone" -> EquipmentSlot.CHEST;
					case "helmet_bone" -> EquipmentSlot.HEAD;
					default -> super.getEquipmentSlotForBone(bone, stack, animatable);
				};
			}

			@Nonnull
			@Override
			protected ModelPart getModelPartForBone(GeoBone bone, EquipmentSlot slot, ItemStack stack, DynamicExampleEntity animatable, HumanoidModel<?> baseModel) {
				return switch (bone.getName()) {
					case "left_boot_bone", "left_armor_leg_bone" -> baseModel.leftLeg;
					case "right_boot_bone", "right_armor_leg_bone" -> baseModel.rightLeg;
					case "right_sleeve_bone" -> baseModel.rightArm;
					case "left_sleeve_bone" -> baseModel.leftArm;
					case "chestplate_bone" -> baseModel.body;
					case "helmet_bone" -> baseModel.head;
					default -> super.getModelPartForBone(bone, slot, stack, animatable, baseModel);
				};
			}
		});
