Hi, I try to register a block with a custom model in Minecraft, but it appears as a full block (and the block under is invisible).

I know that for the entities you have to create a class for the rendering and another the model. I don't know if it's the same for the blocks and if yes I don't know how to convert a JSON file for the model that I made with Blockbench into java class.

 

Thanks for your help.

 

Note: I found that in past version there were the functions isOpaqueCube() and isFullCube() that you were overriding but today in 1.15 with voxel it changed but I couldn't find a tutorial on it.

Hello, 

 

Just override getRenderLayer() method in Block class and return BlockRenderLayer.CUTOUT.

 

@Override
public BlockRenderLayer getRenderLayer() {

    return BlockRenderLayer.CUTOUT;

}

 

Let me know if it's working.
Bye.

Thanks for your answer but there is no such function the block class. And actually 

BlockRenderLayer 

Doesn't even exist.

Okay I think I made some progress: I think I need to override those functions 

 

	public static final AxisAlignedBB BASIC_AABB = new AxisAlignedBB(0D, 0D, 0D, 1D, 1D, 1D);

	@Override
	public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
		// TODO Auto-generated method stub
		return VoxelShapes.create(BASIC_AABB); 
	}
	
	@Override
	public VoxelShape getRenderShape(BlockState p_196247_1_, IBlockReader p_196247_2_, BlockPos p_196247_3_)
	{
		return VoxelShapes.create(BASIC_AABB); 
	}
	
	@Override
	public VoxelShape getCollisionShape(BlockState state, IBlockReader worldIn, BlockPos pos,
			ISelectionContext context) {
		
		return VoxelShapes.create(BASIC_AABB); 
	}
	
	@Override
	public VoxelShape getRaytraceShape(BlockState state, IBlockReader worldIn, BlockPos pos) {
		return VoxelShapes.create(BASIC_AABB); 
	

 

 

But I don't really know how to use them.

Step 1: Do you know what an axis aligned bounding box is?
Step 2: Create axis aligned bounding boxes that roughly approximate your model's total volume.

Well, my cube is a full cube so, I would say that the bounding box (the total volume) is basically a cube size.

 

 

But as you can see it not take in consideration the gap between the feet of the table and it even consider it as a full block since the block underneath is not rendered. I basically want to do like a hopper or a cauldron:

So: 1 I don't know because I couldn't find any tutorial about this.

2: the total volume is a full block.

Ok found it, I have to define multiple AABB that define the edges of the block and then combine all of them in one voxel shape:

 

public static final AxisAlignedBB FEET1_AABB = new AxisAlignedBB(0D, 0D, 0D, 2D/16D, 15D/16D, 2D/16D);
	public static final AxisAlignedBB FEET2_AABB1 = new AxisAlignedBB(14D/16D, 0D, 0D, 16D/16D, 15D/16D, 2D/16D);
	public static final AxisAlignedBB FEET3_AABB1 = new AxisAlignedBB(0D, 0D, 14D/16D, 2D/16D, 15D/16D, 16D/16D);
	public static final AxisAlignedBB FEET4_AABB1 = new AxisAlignedBB(14D/16D, 0D, 14D/16D, 16D/16D, 15D/16D, 16D/16D);
	public static final AxisAlignedBB TOP_AABB1 = new AxisAlignedBB(0D, 15D/16D, 0D, 16D/16D, 16D/16D, 16D/16D);
	
	public static VoxelShape shapeMain;
	
	//Initializing blocks property
	public Research_basic() {
		super("research_basic", Block.Properties.create(Material.WOOD).hardnessAndResistance(1.f, 5.f).variableOpacity(), ModTypes.STATIONS);
		

		VoxelShape shape1 = VoxelShapes.create(FEET1_AABB);
		VoxelShape shape2 = VoxelShapes.create(FEET2_AABB1);
		VoxelShape shape3 = VoxelShapes.create(FEET3_AABB1);
		VoxelShape shape4 = VoxelShapes.create(FEET4_AABB1);
		VoxelShape shape5 = VoxelShapes.create(TOP_AABB1);
		
		shapeMain = VoxelShapes.combine(shape1, shape2, IBooleanFunction.OR);
		shapeMain = VoxelShapes.combine(shapeMain, shape3, IBooleanFunction.OR);
		shapeMain = VoxelShapes.combine(shapeMain, shape4, IBooleanFunction.OR);
		shapeMain = VoxelShapes.combine(shapeMain, shape5, IBooleanFunction.OR);
	}
	
	@Override
	public VoxelShape getShape(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
		// TODO Auto-generated method stub
		return shapeMain;
	}
	
	
	@Override
	public VoxelShape getRenderShape(BlockState state, IBlockReader worldIn, BlockPos pos)
	{
		return shapeMain;
	}
	
	
	@Override
	public VoxelShape getCollisionShape(BlockState state, IBlockReader worldIn, BlockPos pos,
			ISelectionContext context) {
		
		return shapeMain;
	}

 

So now it works perfectly, thanks for your help guys.
