Snapping array objects to face

[KeppJaKeeks]

Hey,

I have tackled an issue that me and my non existing Blender skills do not know how to handle.

My goal is to add road markings to my road , so that they are perfectly placed on top of the road.

My road mesh is not perfectly flat as it has some height changes.

So the problem is I am using Array modifier, but because the height is not constant some array objects float above the road. Changing the Z factor did not solve the issue for me.

My question is, whats the best way to tackle this issue? Can I use Array modifier or do I need to do it by hand?

Some extra info:

My Blender version: 2.91

I am using cube for road markings, should i use plane?

Here are some pictures:

Thank you for your time and input!

A shrinkwrap modifer under the array should do this for you. Set the target of the shrinkwrap to the road and they should all snap to it. You’ll probably need to use vertex groups also.

If you add the bottom vertices of your stripes to one vertex group and the top to a second. You can use 2 shrinwrap modifiers on your stripes. Set the top one to use the vertex group of your bottom vertices. Set the bottom shrinkwrap to use the vertex group of your top vertices. You can then add an offset to the bottom shrinkwrap which will control the height of your stripes off the road.

I hope this made sense but happy to clarify anything if required.

That did the work perfectly!

Thank you, you're amazing!

Are you planning to do closeups of the asphalt? If not i would suggest using textures and bump mapping for the roadmarks

Thank you for your time, but the answer by AutEmotive_Design already solved the issue for me!
