I've done this hundreds of times in 2.7x but in 2.81 I just can't get it to work no matter what I've tried. Sample file attached. I have a simple object I want to array to be, say, 5 kilometers long. I have bezier curve I want it to follow. It just doesn't work and gets twisted and distorted in weird ways. What on earth is wrong... Same scale, same origins, same orientations. What I want is to make it follow the path of the bezier curve, like a road.

There are two things that cause trouble:

1. Array orientation (little trouble)
Your array is facing the wrong way.
Just rotate it like this and set the Relative offset on the X axis.

2. Curve radius (big trouble)
The curve radius is set to 200 (waaay too high), which causes significant distortion.
Either change the curve radius to 1.
Or uncheck Radius in the curve properties.

Change curve radius to 1.

Or disable radius influence altogether

  • $\begingroup$ That is not correct. Your object is flipped twice. It should look like road from above. Not that thing that is rotated 90 degrees and arrayed to wrong direction (Y+ should be forward). $\endgroup$ – user79164 Jan 18 at 10:10
  • $\begingroup$ The thing I just can't figure out is why is there some scaling when certain defoirmation axis and relative offset combinations are used. Where does that come from?? $\endgroup$ – user79164 Jan 18 at 11:11
  • $\begingroup$ Do you have explanation why the Y-direction does not work? $\endgroup$ – user79164 Jan 18 at 11:27
  • $\begingroup$ Well, it works as expected. It's just it in the wrong direction - the width of the road, instead of length :). $\endgroup$ – Jachym Michal Jan 18 at 11:32
