Make sure to have a `VoxelViewer` node in the scene under the camera, and you should see this:
![Custom stream](images/custom-stream.jpg)
Though `VoxelBuffer.fill()` is probably not what you want to use, the above is a quick example. Generate_block generally gives you a block of 16x16x16 cubes to fill all at once, so you may also use `VoxelBuffer.set_voxel()` to specify each one individually. You can change the channel to `VoxelBuffer.CHANNEL_SDF` to get smooth voxels using another mesher such as `VoxelMesherTransvoxel`.
