Your material has additional outputs set to 0 (default), you need to increase that value to the number of outputs you need. Say if you want to plug the tiles map to diffuse, roughness and displacement, you need to set additional outputs to 2, so it will be one default output + 2 additional. You can read this help article if you want to learn more about multiple outputs in Corona:

You can increase noise contrast by adjusting its threshold settings - decrease
high and increase
low. In my case it was something like 0,5 high and 0,49 low. If you shift threshold towards high or low, you will get more blacks or lows, so something like 0,35 high and 0,34 low will get you high contrast and predominantly white colours. Feel free to experiment with the values until you get result that you need. If you'll get the pattern right, but won't be happy with its placement, try to adjust
phase. Hope that helps.
