Hi there! I'm hosting a spigot 1.11 server, and I'm making a client mod which changes the model of entities with certain names.

Since it is a client-side mod, I can't bind the model on a custom Item class like most tutorials.  

I've figured a way to load and bake the model, cache it, then render it in RenderLivingEvent.Pre event. Here's the result, a horse "disguised" as the model:

The only problem here is, obviously, the model won't be loaded, everything else works like a charm.

 

I have uploaded all relevant code and assets to a repository: https://github.com/SmilingTrickster/rendercloudmodel

 

Here's where the model is loaded and cached: https://github.com/SmilingTrickster/rendercloudmodel/blob/master/java/com/mcorg/maccaronne/client/resources/model/ModelResource.java#L44

Here's the rendering code entry: https://github.com/SmilingTrickster/rendercloudmodel/blob/master/java/com/mcorg/maccaronne/client/equip/MountModelRenderer.java#L60

Any help is greatly appreciated

bump.

Don't use Minecraft::getItemModelMesher. Prone to issues. Forge has since several versions now included the ModelLoader as a more reliable Model handler.

 

This is how I manually load a (normal) IBakedModel.

To load a .OBJ model, you need to call OBjLoader::loadModel instead of ModelLoaderRegistry::getModel.

After five hours of trial and errors, now at least something is rendered!

        if (bakedModel == null) {

                model = OBJLoader.INSTANCE.loadModel(new ResourceLocation("eodmod", "models/" + resourceLocation + ".obj"));
                bakedModel = model.bake(TRSRTransformation.identity(), DefaultVertexFormats.ITEM,

        }
    }

    boolean message = false;

    public void renderModel(Entity entity, double offsetX, double offsetY, double offsetZ, double pitch, double yaw) {
        GlStateManager.pushMatrix();
        GlStateManager.pushAttrib();
        GlStateManager.color(1f, 1f, 1f, 1f);
        GlStateManager.rotate((float) -yaw, 0.0F, 1.0F, 0.0F);
        GlStateManager.rotate((float) pitch, 0.0F, 1.0F, 0.0F);

        World world = entity.world;
        BlockPos pos = new BlockPos(0, 0, 0);

        Tessellator tessellator = Tessellator.getInstance();
        VertexBuffer buffer = tessellator.getBuffer();
        BlockPos blockPos = new BlockPos(offsetX, offsetY, offsetZ);
        IBlockState blockState = world.getBlockState(blockPos);
        List<BakedQuad> quads = bakedModel.getQuads(blockState, null, 0);
        if (quads.isEmpty()) return;
        VertexFormat format = quads.get(0).getFormat();

        tessellator.getBuffer().begin(GL11.GL_QUADS, format);
        Minecraft.getMinecraft().getBlockRendererDispatcher().getBlockModelRenderer().renderModelSmooth(
                world,
                getBakedModel(),
                blockState,
                pos,
                buffer, false, 0);
        tessellator.draw();

        GlStateManager.color(1f, 1f, 1f, 1f);
        GlStateManager.popAttrib();
        GlStateManager.popMatrix();
    }
}

 

 

However, some faces of the model are missing, and the texture is missing.

I wonder how I suppose to use 'Function<ResourceLocation, TextureAtlasSprite>' in IModel::bake? Where should the png file be?

 

Some debug message from OBJLoader pops up when the model is loaded:

The obj model is exported from 3dsmax. Here's how it's supposed to look like

Did this ever get resolved?
