The problem is i didn’t expect the plain effector to create a bulge, i set the deformation to Points. and set the transform parameter to move 50px on the X axis. and i expected all the point to move 50px on that axis. but they didn’t.
as its showed in the first screenshot it just created a bulge ☹
I now my English isn’t that a great, and am making it harder for you to understand what am i going for,
So thank you again for your time.
