Array isn't following curve I have set up an array modifier and a bezier curve which the array is following. My spheres aligned themselves in a straight line for the length of the curve, however they are not following the curve exactly.



This is not a duplicate. I have followed every answer of the already
posted questions and none of them worked.
Add a Curve modifier and, in this modifier, choose the Bezier Curve as the Object
You've changed the radius of the curve vertices, so select the curve, enter in Edit mode, select all, open the 3D view properties panel on the right of the 3d view (press N), and in Transform choose a Mean Radius of 1
