building game changes UV spaces for generated mesh

[_Aka_]

Hi again
Your issue is indeed intriguing. Like you said, you exported the Curvy generated track to an external asset, and removed Curvy from your project, so Curvy should not be the cause of this issue. Here are some leads to try to find a solution:

1. Have you exported the meshes using the export button in the Curvy Generator's toolbar? If not, please try again while using this method.
   
2. Make a project with only a scene showing that mesh. Does building it create the issue?
   • If yes, then try opening the mesh outside Unity's editor. Does the problem occurre there too?
     • If yes, can the problem be fixed in that outside software?
       • If yes fix it and reexport the mesh
         
       • If not, send me the mesh and everything necessary to produce the mesh with Curvy
         
     • If no, open a Unity issue, stating that this mesh works fine outside unity, in edit mode but not in play mode, while attaching the project
       
   • If no, then strip your original project gradually until finding what to be deleted to solve the issue.
     

Also, if possible, try different unity versions. If the problem comes from Unity, a different version might solve/avoid the issue
