Hello:
I am trying to implement field-of-vision such that the terrain not within view of the protagonist is not visible. That was out-of-the-box in Godot 3 with light2D mode set to 'MASK', but in Godot 4 the 'mode' was replaced with 'BlendMode', which doesn't have the mask, it only has 'mix', 'add' and 'subtract'.
What is the godot 4 way to implement light shadow masking?
