I am trying to have an object's position map to a curve. I have drawn a curve, extended it a few times using an array modifier, converted it to a mesh to apply the modifier and then back to a curve, and created a cylinder to travel along the curve.
When I apply the curve modifier, the object disappears in object mode and isn't visible in render, but is still visible, unmodified, in edit mode. Changing the deform axis makes no difference.
If I remove the modifier, the cylinder reappears. Strangely, if I open a new blank project and use the same technique, it works fine. So it seems to be an issue just in this project. Is there anyone with any idea of what is going on or why my object might be disappearing/not mapping?
