So, I actually got some progress done on this (looking through the system). And, the model renders, but with two problems: first is MAJOR FPS drop (150 to 3). I am guessing it is because I add the layer in my event constantly, but I am not sure. Secondly, the model scale is incorrect, as shown here (it's rendered too small, just below the body which is where it needs to be):

My classes:

Layer renderer base (for ease when I need to render different backpack models):

package com.happykiller.weightlimit.client.renderer;

import com.happykiller.weightlimit.main.ModReference;
import com.happykiller.weightlimit.render.models.ModelMediumBackpack;
import net.minecraft.client.model.ModelBase;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.renderer.entity.RendererLivingEntity;
import net.minecraft.client.renderer.entity.layers.LayerRenderer;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.util.ResourceLocation;[/p]
public abstract class LayerBackpackBase implements LayerRenderer {
 protected T field_177186_d;
 private final RendererLivingEntity<?> renderer;
 private float alpha = 1.0F;
 private float colorR = 1.0F;
 private float colorG = 1.0F;
 private float colorB = 1.0F;
 
 public LayerBackpackBase(RendererLivingEntity<?> rendererIn) {
 this.renderer = rendererIn;
 this.initBackpack();
 }
 
 public void doRenderLayer(EntityLivingBase entitylivingbaseIn, float p_177141_2_, float p_177141_3_, float partialTicks, float p_177141_5_, float p_177141_6_, float p_177141_7_, float scale) {
 renderLayer(entitylivingbaseIn, p_177141_2_, p_177141_3_, partialTicks, p_177141_5_, p_177141_6_, p_177141_7_, scale);
 }
 
 private void renderLayer(EntityLivingBase entitylivingbaseIn, float f1, float f2, float partialTicks, float p_177182_5_, float p_177182_6_, float p_177182_7_, float scale) {
 T t = this.field_177186_d;
 t.setModelAttributes(this.renderer.getMainModel());
 t.setLivingAnimations(entitylivingbaseIn, f1, f2, partialTicks);
 t = (T)new ModelMediumBackpack(6.0F);
 this.setShownLayer(t);
 
 this.renderer.bindTexture(new ResourceLocation(ModReference.MOD_RL + "/models/backpack/MediumBackpack.png"));
 
 GlStateManager.color(this.colorR, this.colorG, this.colorB, this.alpha);
 t.render(entitylivingbaseIn, f1, f2, p_177182_5_, p_177182_6_, p_177182_7_, scale);
 }
 public boolean shouldCombineTextures() {
 return false;
 }
 
 public abstract void initBackpack();
 protected abstract void setShownLayer(T model);
}

LayerBipedBackpack (the layer I add):

package com.happykiller.weightlimit.client.renderer;
import net.minecraft.client.model.ModelBiped;
import net.minecraft.client.renderer.entity.RendererLivingEntity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
@SideOnly(Side.CLIENT)
public class LayerBipedBackpack extends LayerBackpackBase<ModelBiped> {
public LayerBipedBackpack(RendererLivingEntity<?> rendererIn) {
 super(rendererIn);
 }
public void initBackpack() {
 this.field_177186_d = new ModelBiped(0.5F);
 }
protected void setShownLayer(ModelBiped model) {
 model.bipedBody.showModel = true;
 }
}

My Event:

 @SubscribeEvent
 public void onRenderEntity(RenderLivingEvent.Post event) {
 //System.out.println("Render Event Called");
 
 if(event.entity instanceof EntityPlayer) {
 EntityPlayer player = (EntityPlayer)event.entity;
 
 event.renderer.addLayer(new LayerBipedBackpack(event.renderer));
 
 LogHelper.logInfo("Layer Added");
 }
 }

I hope someone can help me here, I don't understand this plague of the new layer system. It seems no one ever has a clue on what to do here. :/

Thank you for the reply! My only problem with this seems to be that I can not get an instance of RendererLivingEntity (which I need for my layer class):

(Minecraft.getMinecraft().getRenderManager().getSkinMap().get("default")).addLayer(new LayerBipedBackpack(need RenderLivingEntity instance for the player));

If you know how to get this, I would be very grateful!

I have actually been programming in Java for two years, and someone on the MinecraftForge forums pointed out this silly mistake I made. Thank you for the reply!
