Hi, so I'm trying to add a custom boss who holds a sword. I made a model in blockbench and imported it and coded a renderer. the entity renders fine but as soon as I give it the sword the game crashes 

 

Model:

Spoiler 
HiemModel.java

package whfo.whfo.Renderers.model;
// Made with Blockbench 3.9.3
// Exported for Minecraft version 1.15 - 1.16 with MCP mappings
// Paste this class into your mod and generate all required imports


import com.mojang.blaze3d.matrix.MatrixStack;
import com.mojang.blaze3d.vertex.IVertexBuilder;
import net.minecraft.client.renderer.entity.model.EntityModel;
import net.minecraft.client.renderer.model.ModelRenderer;
import net.minecraft.entity.Entity;
import whfo.whfo.entities.EntityHiem;

public class HiemModel<E extends EntityHiem> extends EntityModel<E> {
    private final ModelRenderer bb_main;

    public HiemModel() {
        textureWidth = 64;
        textureHeight = 64;

        bb_main = new ModelRenderer(this);
        bb_main.setRotationPoint(0.0F, 24.0F, 0.0F);
        bb_main.setTextureOffset(16, 28).addBox(-4.0F, -9.0F, -2.0F, 4.0F, 9.0F, 4.0F, 0.0F, false);
        bb_main.setTextureOffset(0, 28).addBox(0.0F, -9.0F, -2.0F, 4.0F, 9.0F, 4.0F, 0.0F, false);
        bb_main.setTextureOffset(30, 0).addBox(-4.0F, -18.0F, -2.0F, 8.0F, 9.0F, 4.0F, 0.0F, false);
        bb_main.setTextureOffset(16, 15).addBox(4.0F, -18.0F, -2.0F, 4.0F, 9.0F, 4.0F, 0.0F, false);
        bb_main.setTextureOffset(0, 15).addBox(-8.0F, -18.0F, -2.0F, 4.0F, 9.0F, 4.0F, 0.0F, false);
        bb_main.setTextureOffset(0, 0).addBox(-4.0F, -26.0F, -3.0F, 8.0F, 8.0F, 7.0F, 0.0F, false);
    }

    @Override
    public void setRotationAngles(E entityIn, float limbSwing, float limbSwingAmount, float ageInTicks, float netHeadYaw, float headPitch) {

    }

    @Override
    public void render(MatrixStack matrixStack, IVertexBuilder buffer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha){
        bb_main.render(matrixStack, buffer, packedLight, packedOverlay);
    }

    public void setRotationAngle(ModelRenderer modelRenderer, float x, float y, float z) {
        modelRenderer.rotateAngleX = x;
        modelRenderer.rotateAngleY = y;
        modelRenderer.rotateAngleZ = z;
    }
}

 

 

 

Renderer:

Spoiler 
HiemRenderer.java

package whfo.whfo.Renderers;

import net.minecraft.client.renderer.entity.EntityRendererManager;
import net.minecraft.client.renderer.entity.MobRenderer;
import net.minecraft.client.renderer.entity.layers.HeldItemLayer;
import net.minecraft.util.ResourceLocation;
import whfo.whfo.Renderers.model.HiemModel;
import whfo.whfo.Whfo;
import whfo.whfo.entities.EntityHiem;

public class HiemRenderer extends MobRenderer<EntityHiem, HiemModel<EntityHiem>> {

    public static final ResourceLocation TEXTURE = new ResourceLocation(Whfo.MODID, "textures/entity/hiem/hiem.png");

    public HiemRenderer(EntityRendererManager renderManagerIn) {
        super(renderManagerIn, new HiemModel<>(), 0.7f);
        this.addLayer(new HeldItemLayer(this));
    }

    @Override
    public ResourceLocation getEntityTexture(EntityHiem entity) {
        return TEXTURE;
    }
}
