Mesh error when uploading to roblox studio

when I create a octogon in blender (I add a circle mesh then change the vertices) it appears transparent when i upload it into roblox studio, I don’t know what the issue is,

anyone know?

Is it possible to provide an image? It makes it way easier to see what you mean.

Enable DoubleSided. If that fixes the issue, invert your vertices.

how would I do that?

It can be found it the properties tab of the mesh.
