Custom Blocks
materialThis is a startup script.
onEvent('block.registry', event => {
  event.create('test_block').material('glass').hardness(0.5).displayName('Test Block')
})
The texture for this block has to be placed in kubejs/assets/kubejs/textures/block/test_block.png.
If you want a custom block model, you can create one in Blockbench and put it in kubejs/assets/kubejs/models/block/test_block.json.
