Incorrect Scaling? (BP for mesh along spline)

Development Discussion Blueprint Visual Scripting
#1

Hello,

As the title states, I am trying to make a mesh appear along a spline.
I followed a tutorial and got the spline working in editor together with the mesh.
The problem is though, its scaling really weird and I dont know why since im new to Blueprints…

The mesh is made in max and exported as FBX.

State2: http://puu.sh/sgfRa/419acf2f18.jpg

According to the tutorial I watched, this should work(but the video is 2 years old so I didn’t count on it)
I was expecting it to be as in that video where the entire spline is made up out of that object.

Here is the video of what I would like to achieve:https://youtube.com/watch?v=7YUxM0NDWRY
Thank you for your help,
Kind Regards,
Torben

You might want to try this tutorial video instead: https://www.youtube.com/watch?v=kJyWSzfwEk8

The scaling looks ok, you seem to have messed up the axis. Try the linked tutorial and pick the correct forward axis.

Wow ok, seems I was using a bad tutorial, wonder if it was just outdated or something…

Thx man that really helped me out, I d have to model all of the pipes and curves otherwise xD.

One more thing though, when I make a 90 degree angle the shape gets contorted pretty badly

Would you know what is up with that as well?

Looks like tangents and/or up axis are getting messed up. Try something closer to this (see the tangent scale as well as set roll comments?) : https://forums.unrealengine.com/attachment.php?attachmentid=71426&d=1451055591
