Importing issue (i just wanna insert 4 simple circles and thats it)

As the title says, all I wanna do is just insert 4 simple circles like this:


Yet for some reason, it comes out looking like this:

I have no idea whats going on, but I don’t know what to do anymore. Any help would be appreciated, thanks.

try to make the circles thicker (maybe because the circles are to thin)

Make them thick enough to the point where they are almost spheres.

Nope, that doesn’t fix anything:

Is the issue why they aren’t circle in shape? I would suggest importing circles made on an external software.

You can try Double Sided in the properties of the MeshPart

Doesn’t work, the missing faces don’t show up regardless of whether DoubleSided is on or not.

You can also try to flip the normals by the following steps:

  1. Select the mesh in blender and press Tab to open the edit mode.
  2. Press A to select everything in the mesh.
  3. Go to the button called Mesh at the top of the screen.
  4. Go to the Normals button.
  5. You can try the following buttons to fix the mesh:

Try triangulating them before exporting.

Try triangulating before exporting like the reply above me says and also apply all transformations by selecting the object in blender > ctrl + a > apply all transformations. Then re-export and import.

This might be because the meshes have very few vertices
Roblox automatically triangulates everything you import, probably there is not enough geometry to do a clean triangulation so this happens

You can try:

  • Subdivide the circles
  • Extrude them to add a bit of thickness
  • Import the circles separately, not in 1 single mesh
  • Make sure your mesh has a clean topology, this means, that the circle face in edit mode is clean and does not have a lot of random and messy vertices, if it is the case, you can select all, tab X and select “Limited Dissolve”
