Would there be a problem if my mesh was only a plane in blender

I have this blender model I had made, however, it is made of a plane and would therefore be extremely thin, would this cause a problem when in roblox? (Not so obvious problems i mean), and If so, how would I make it less thin?

If you are trying to upload the mesh which is very thin, it is very likely that you may encounter problems with inverted normals so I would highly suggest that you add a solidifier to it and as stated by @TaBigMemesGuy it may cause in-game issues in terms of its hitbox ect. You can easily solve this by adding a solidify modifier under the Modifier Properties. You may adjust the thickness of the plane to your own liking or leave it as it is.

The hitbox might be inaccurate in-game which could cause some bugs like incorrect collision or gravity miscalculation. This shouldn’t be of much importance if the plane is CanCollide off or Anchored.
