How to make a texture visible when illuminated with a shadow

How do I make the sprite texture visible in this example? Now all objects are dark, as is the shadow. https://www.construct.net/en/tutorials/multiple-colored-shadow-casting-lights-1107

Put the Shadow Light object on a separate layer beneath the sprites. You can also set its opacity this way by adjusting the layer opacity.

Thanks for the reply. Could you show this in an example? I didn't succeed

The multiply effect on Background layer was causing the blocks to not be visible. I moved them to Top layer.

Thanks. And how to make objects become visible only when they hit the radius of light and at the same time cast a shadow?
