Not sure how should I properly use the bend modifier

I wish to bend it to form a disk.

I need to do it this way because I want the UV to follow the circle (like, polar coordinates)

The modifier seems not working as intended. I can’t figure out how to bend it properly

Use an Empty to controll the bending:

Guys, I figured it out.

I need to rotate the plane 90 degrees.

Because the modifier only bends the mesh starting from Y axis.

Thank you.

I figured it out. It is because the bend modifier only bends along Y axis. I rotated the mesh 90 degrees and it’s solved.
