I have been working with custom models for a while now, and Its only until now I have been stumped, I did a lot of Trial and error and worked out part of the issue but some still remain. Anyways, the problem is making the leaves move with the head as a whole, I have got the nose to do it but I just cant get the leaves to do it.

package com.phantasyrealms.model;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.entity.Entity;

public class ModelPoisonLilyMob extends ModelBase
{
  //fields
    ModelRenderer head;
    ModelRenderer body;
    ModelRenderer nose;
    ModelRenderer Leaf1;
    ModelRenderer Base;
    ModelRenderer Leaf2;
    ModelRenderer Leaf3;
  
  public ModelPoisonLilyMob()
  {
    textureWidth = 64;
    textureHeight = 32;
    
      head = new ModelRenderer(this, 0, 0);
      head.addBox(-4F, -8F, -7F, 8, 8, ;
      head.setRotationPoint(0F, -7F, -1F);
      head.setTextureSize(64, 32);
      head.mirror = true;
      setRotation(head, 0F, 0F, 0F);
      body = new ModelRenderer(this, 56, -1);
      body.addBox(-1F, 0F, -1F, 2, 30, 2);
      body.setRotationPoint(0F, -7F, 0F);
      body.setTextureSize(64, 32);
      body.mirror = true;
      setRotation(body, 0F, 0F, 0F);
      nose = new ModelRenderer(this, 32, 6);
      nose.addBox(-2F, -6F, -15F, 4, 4, ;
      nose.setRotationPoint(0F, -7F, -1F);
      nose.setTextureSize(64, 32);
      nose.mirror = true;
      setRotation(nose, 0F, 0F, 0F);
      Leaf1 = new ModelRenderer(this, 37, 19);
      Leaf1.addBox(-6F, 6F, -3F, 6, 10, 1);
      Leaf1.setRotationPoint(0F, -7F, -1F);
      Leaf1.setTextureSize(64, 32);
      Leaf1.mirror = true;
      setRotation(Leaf1, -2.792527F, 0F, 0.9250245F);
      Base = new ModelRenderer(this, 0, 18);
      Base.addBox(-6F, -1F, -6F, 12, 2, 12);
      Base.setRotationPoint(0F, 23F, 0F);
      Base.setTextureSize(64, 32);
      Base.mirror = true;
      setRotation(Base, 0F, 0F, 0F);
      Leaf2 = new ModelRenderer(this, 37, 19);
      Leaf2.addBox(0F, 6F, -3F, 6, 10, 1);
      Leaf2.setRotationPoint(0F, -7F, -1F);
      Leaf2.setTextureSize(64, 32);
      Leaf2.mirror = true;
      setRotation(Leaf2, -2.792527F, 0F, -0.9250245F);
      Leaf3 = new ModelRenderer(this, 37, 19);
      Leaf3.addBox(-3F, 0F, -1F, 6, 10, 1);
      Leaf3.setRotationPoint(0F, -7F, -1F);
      Leaf3.setTextureSize(64, 32);
      Leaf3.mirror = true;
      setRotation(Leaf3, -0.418879F, 0F, 0F);
  }
  
  public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5)
  {
    super.render(entity, f, f1, f2, f3, f4, f5);
    setRotationAngles(f, f1, f2, f3, f4, f5, entity);
    head.render(f5);
    body.render(f5);
    nose.render(f5);
    Leaf1.render(f5);
    Base.render(f5);
    Leaf2.render(f5);
    Leaf3.render(f5);
  }
  
  private void setRotation(ModelRenderer model, float x, float y, float z)
  {
    model.rotateAngleX = x;
    model.rotateAngleY = y;
    model.rotateAngleZ = z;
  }
  
  public void setRotationAngles(float p_78087_1_, float p_78087_2_, float p_78087_3_, float p_78087_4_, float p_78087_5_, float p_78087_6_, Entity p_78087_7_)
  {
  float f6 = (180F / (float)Math.PI);	  
  this.head.rotateAngleX = p_78087_5_ / (180F / (float)Math.PI);
      this.head.rotateAngleY = p_78087_4_ / (180F / (float)Math.PI);
      this.nose.rotateAngleX = this.head.rotateAngleX;
      this.nose.rotateAngleY = this.head.rotateAngleY;
      this.Leaf1.rotateAngleX = this.head.rotateAngleX;
      this.Leaf1.rotateAngleY = this.head.rotateAngleY;
      this.Leaf2.rotateAngleX = this.head.rotateAngleX;
      this.Leaf2.rotateAngleY = this.head.rotateAngleY;
      this.Leaf3.rotateAngleX = this.head.rotateAngleX;
      this.Leaf3.rotateAngleY = this.head.rotateAngleY;


  }

}

 

It is suppose to look like this

Instead it looks like this

Because the leaves had initial rotations on them that you're overwriting when it animates.

What do you mean? the setRotation? or the setRotationPoint?

setRotation(head, 0F, 0F, 0F); //angle X = 0
setRotation(Leaf1, -2.792527F, 0F, 0.9250245F); //angle X = -2.79, not the same
...
this.Leaf1.rotateAngleX = this.head.rotateAngleX; //make them the same

Alright so I get that, now I dont know what to do about it, In the Techne I positioned the rotation point in the same spot, when I did that with the nose and then set it to the head it worked just fine. and then before I set the rotation point to the same as the head it was the same problem. So should I again adjust the model of it?

Why don't you make the leaves children of the head? Then whenever the head moves, you don't have to do anything and they will automatically rotate / move with it.

Because they have DIFFERENT BASE ROTATIONS. It had Jack Fucking Squat to do with the rotation POINT, but everything to do with the rotation VALUE. The head and nose use the same values, the leaves DON'T.

 

Also what coolAlias said.

Yeah the addChild did it, but I decided not to use the mob anyway thanks for your help though.
