How can I hide a SpineSprite when it's outside of lit areas?

whereamI

Hi, I'm using a SpineSprite in Godot 4 and I want it to be completely invisible when it's outside of light, and only visible when it's inside a lit area.

With a regular Sprite2D, I can use a CanvasItemMaterial with light_mode = LIGHT_ONLY, and it works perfectly.

But with SpineSprite, this approach doesn't seem to work as expected — the character doesn't disappear in darkness, or sometimes just turns black instead of being fully invisible.

Is there a correct way to achieve LIGHT_ONLY behavior with SpineSprite?
I'd appreciate any help or examples that show how to make it work properly.

Thanks in advance!

To achieve the LIGHT_ONLY behavior with a SpineSprite in Godot, you can use custom materials to control how the SpineSprite interacts with lighting. You can set a custom material for each supported Spine blend mode in the Materials property section of the SpineSprite. This allows you to apply a CanvasItemMaterial with the light_mode set to LIGHT_ONLY, similar to what you would do with a regular Sprite2D. If the SpineSprite is not responding as expected, ensure that the normal maps are correctly set up and that the material is properly applied to the SpineSprite or its slots using a SpineSlotNode.
