Why is my asset appearing as non-transparent? I just downloaded a 3d plant asset in FBX format from Megascans and this is the way my model appears.

The wheat seems to not be flat, and non-transparent. How do I make it transparent around the grains, and not as rectangular?
Looking at the material, nothing is connected to the alpha input of the shader. Connect this, and then make sure in the material settings that alpha mode is set to “hashed” and not “opaque”.
