Mesh along spline deforming incorrectly

So I have been trying to use the road blueprint from [this][1] tutorial to generate rails along splines. The problem is that the mesh deformation is not working properly on my model. I think it is either a problem with my blender mesh or the generation blueprint.

The short section of track has no problem deforming as a Spline Mesh Component though…

I’m having the same issue with tangents but I haven’t exhausted all my ideas to fix it. I was wondering if you got around to fixing your issue? I’m adding in multiple spline meshes in-between spline points and tangent scale impacts it a lot. I’m wondering if its just because of how low poly the object is that it’s not able to properly deform.

I’ve done two things to give myself options:

  1. I added an editable value that sets my Forward Axis of my spline meshes
  2. I added an editable value that toggles using tangents for my spline meshes

Tangents Enabled

Tangents Disabled

Checked with a mesh that would fit with what you’re doing and it seems turning off tangents worked. At least it was more appealing.

Hey Puppet, any chance you can elaborate on what you did for the TangentsOff image? I’m trying to create a spline mesh blueprint that functions like what you’ve got in that image and I can’t get my meshes to remain parallel like you have. They always deform (like in the Road tutorial). Perhaps a grab of your blueprint? Any help would be most appreciated.

I had a similar problem, the mesh had Nanite enabled. Started working fine when I disabled it.
