Documentation mentions that you can add mask to particles when disscusing Half Extent option but does not say how to add mask. In examples there is particle with mask but I can’t figure out where is that option in the Inspector.

It’s not in the inspector, it’s a button in the toolbar right above the 2D viewport. You can also do it in script with set_emission_points( Vector2Array points ). The point coordinates should be in the -1.0 to 1.0 range.
