I'm trying to create a row of street lights, both the lamp pole and a spot light. Since i can't simply join these two and use an array + curve modifier to set this up (using an array modifier + a curve modifier always deforms the mesh) so i came to the conclusion that working with collections and instances would be my best bet.
To get to my current result i parented the spot to the lamp mesh. Then i parented those two objects to a plane. after that i parented the plane (and so also the lamp mesh and the spot) to a curve that i converted to a mesh. I then activated Instancing for the curve with verts which resulted in something like this:
As you can see the lamps all face the same direction, while i want them to be rotated inwards. There's an option for 'aligning the objects to vertex normal'
but enabling this exposes a multitude of problems:
- Problem 1: it turns out there's two instances of every object. (i have no idea why)
- Problem 2: the street light meshes get deformed.
- Problem 3: the actual lights all face toward the same place
(I drew over the lamp directions with blue arrows for visibility)
If anyone knows how i can get this to work i'd really appreciate it, but other techniques are welcome too.
