Need to change AutoUnwrapSettings at Run-Time

Unwrap settings have to be applied after creation. So you'd do something like this:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.ProBuilder;
3.  
4. public class CreateCubeWithUnwrapSettings : MonoBehaviour
5. {
6.     void Start()
7.     {
8.         var mesh = ShapeGenerator.CreateShape(ShapeType.Cube);
9.  
10.         foreach (var face in mesh.faces)
11.         {
12.             face.uv = new AutoUnwrapSettings()
13.             {
14.                 anchor = AutoUnwrapSettings.Anchor.UpperLeft,
15.                 fill = AutoUnwrapSettings.Fill.Fit,
16.                 scale = new Vector2(0.33f, 0.33f)
17.             };
18.         }
19.  
20.         // Just need to rebuild the UVs, and since we didn't modify vertex count or materials we can skip the `ToMesh`
21.         // invocation.
22.         mesh.Refresh(RefreshMask.UV);
23.     }
24. }
25.
