Cylinders and spheres no longer align correctly when building curves

Hello,

I’m having an issue that I don’t remember existing before. For a long time, I used cylinders to create smooth curves by aligning them to spheres, and everything worked perfectly.

However, it seems that Roblox has changed something about either cylinders or spheres. Now, the parts only align perfectly when they’re at 90-degree angles. At any other angle, there’s always a slight misalignment, making it impossible to create clean, smooth curves like before.

I’ve already verified that:

  • The sphere’s Pivot is correctly centered.
  • The cylinder dimensions are correct.
  • The issue happens consistently, even in a new place.

This workflow used to work flawlessly, so I’m wondering if there was a change to how cylinder or sphere geometry is handled.

Has anyone else experienced this issue, or is there a workaround?

Thanks!

roblox cylinders and spheres aren’t perfectly round, this was always an issue as far i know. the only real solutions that would be worth your time is either make whatever you’re building in blender or replace the parts with smoother cylinder and sphere meshes

If you can, try installing the “Pipes” plugin; it might help you solve this. To see how it works, create a cylinder with a sphere on top to give it a rounded look. Then, copy that cylinder-and-sphere assembly and place the copy wherever you want. Finally, select the sphere from one assembly and the sphere from the other, and click the plugin icon; it will create cylinders of the right size to fit perfectly between the spheres, I hope that helped :))

In the past, this problem didn’t exist.

The same problem is happening. I spoke with another developer, and they told me this might be happening because of Roblox’s new dragger system.

Well, I figured out a way to fix this. Just add another circle to the end of the cylinder that will rotate.


I know this seems cliche, but I highly recommend learning some basic blender and using blender to ease your workflow with pipes. I used to do cylinders/spheres, but you can use a curve modifier on a line in edit mode and easily make pipes/shapes especially with vert bevels it’s not too hard!
