My wheel that i made in blender isn't loading properly

I made a 3d model in blender but when i export it to roblox, part of the model seems transparent.

The inside of the wheel is visible when it should be blocked from the outer layer of the wheel

Enable DoubleSided and see if it fixes

(this fix worked for me when I had this issue)

NO NO NO NO NO!!!

@rafferty05, you have the normals flipped on your Mesh. Basically it’s not built correctly.
Google Blender flip normals for ways to find out how your Faces are flipped.

Using DoubleSided is ONLY intended for use with flat MeshParts like paper or leaves.
Using it where the correct faces meet flipped faces it creates a twist in the mesh rendering which will create shadowed edges at that location on your Part . It also doubles the tris on your MeshParts which causes a bit more load on your graphics card, and possibly lag in your game.

Using DoubleSided like this is kinda like using duct tape to hold the fender on your car. It may work, but it definitely is not the correct way.
