[1.11.2] Loading IBakedModels from custom json file

[grand_gibus]

Hello everyone,

I am trying to make a tile entity special renderer that renders a json model that is not used by a block or an item. I've looked at the RendererItemFrame class, and there this thing:
 

ibakedmodel = modelmanager.getModel(this.itemFrameModel);

 

I've tried but it didn't work, I'm guessing you have to register the model first. My question is, how to do that? If it's not possible that way, how should I do that?
Here is my code:
 

@SideOnly(Side.CLIENT)
public class TileEntityWorkBenchRenderer extends TileEntitySpecialRenderer<TileEntityWorkBench>{
	
	public final Minecraft mc = Minecraft.getMinecraft();
	
	
	@Override
	public void renderTileEntityAt(TileEntityWorkBench te, double x, double y, double z, float partialTicks, int destroyStage){
        try{
        	
            this.mc.getRenderManager().renderEngine.bindTexture(TextureMap.LOCATION_BLOCKS_TEXTURE);
            BlockRendererDispatcher blockrendererdispatcher = this.mc.getBlockRendererDispatcher();
            ModelManager modelmanager = blockrendererdispatcher.getBlockModelShapes().getModelManager();
            IBakedModel ibakedmodel;
			
	        GlStateManager.pushMatrix();
	        
	        GlStateManager.translate(x + 0.5D, y + 1D, z + 0.5D);
	        
	        ibakedmodel = modelmanager.getModel(new ModelResourceLocation(Reference.MOD_ID + ":workbench", "text"));
	
	        GlStateManager.pushMatrix();
	        GlStateManager.translate(-0.5F, -0.5F, -0.5F);
	
	        blockrendererdispatcher.getBlockModelRenderer().renderModelBrightnessColor(ibakedmodel, 1.0F, 1.0F, 1.0F, 1.0F);
	
	        GlStateManager.popMatrix();
	        GlStateManager.translate(0.0F, 0.0F, 0.4375F);
	        GlStateManager.popMatrix();
        }catch(Exception e){
        	e.printStackTrace();
        }
	}
}

The blockstate file:
 

{
    "variants": {
        "normal": { "model": "modtest:workbench" },
        "text": { "model": "modtest:workbench_text" }
    }
}

I've tried to load a model that is used by a block and it works

ibakedmodel = modelmanager.getModel(new ModelResourceLocation(Reference.MOD_ID + ":workbench", "normal"));

Note that I'm still new to modding and that I have no idea if I'm going for the right way.

Thanks!

Well I was planning on using a TESR to render a custom model that would be rotating on top of the normal block model.
(A crafting table with a floating rotating text model on top)

The TESR above is for the model that I'm planning to be rotating, I just haven't done it yet when I saw that the model wasn't loading. The fixed model is just the block of the tileentity. Also, could you explain what a FastTESR is please?

Ok, thanks for the answer! I would like to directly  get the model and bake it if possible, but for me the ModelLoader.getModel method doesn't exist. Has it been replaced in 1.11.2?
