How to keep shadows while having transparency

I want the mesh to keep casting shadows in its original shape, regardless of its transparency.
However, when the opacity mask is set to 0, the shadow also disappears.
Could you please tell me how to solve this issue?

i can’t remember the option, but there’s a “hidden shadow” on the mesh component. and there’s an option on the material to deal with shadows on transparency (off by default)

there’s also a node for the shadowpass, where you might fake the transparency to what you want.
