Hello, I'm experiencing with the new Rendering Registry for Forge 1.8

And I'm trying to load a B3D model file generated by Blender using the add-on provided by RainWarrior https://github.com/RainWarrior/B3DExport

But the B3DLoader is giving me this error:

[XX:XX:XX] [Client thread/ERROR] [FML]: No root mesh in model tests:models/item/Test.b3d and no mesh name in location, skipping

 

Does anyone have a clue on how to fix it?

I checked everywhere on github for a mod using this method and apparently no one is using it.

I looked at the source and the error seems to come from here:

        if(!(model.getRoot().getKind() instanceof Mesh))
        {
            FMLLog.severe("No root mesh in model %s and no mesh name in location, skipping", modelLocation);
            return ModelLoaderRegistry.getMissingModel();
        }

 

Here's the code which is loading the model in my proxy:

IModel model = ModelLoaderRegistry.getModel(new ResourceLocation(BaseReferences.MODID+":item/Test.b3d"));

 

Any help is appreciated! 

I'm not sure if you still need help but your model needs to have 1 object that is named "mesh"

Like this:

Sorry to resurrect an old thread, but this is the first search result for that error and I think it's good to keep the info in one place.

 

I think the problem is not the name of the mesh, but whether the exported model contains a single object. The B3DLoader expects the root node to be a mesh, but if you export several mesh objects together, you get something like this

 

BB3D
  NODE
    name=ROOT
    NODE
      name=Body
      MESH
      ANIM
      NODE
        <bones>
    NODE
      name=LeftArm
      MESH
      ANIM
      NODE
        <bones>
    <etc>

 

However if you join the objects into one mesh (ctrl+J), you get

 

BB3D
  NODE
    name=Body
    MESH
    ANIM
    NODE
      <bones>
