RingMap  is mainly used to UV Map quad strips,so  you can know it is very good at  texturing curved roads

RingMap also can  UV Map other  various types of pavements ,such as grass,squre.
RingMap works in the same way as  [Road Paver],but the later is more suit for a big amount of UV Mapping tasks.

UV mapping for road

Observe the topology of this kind of surfaces ,you can find they can be created by a path and a section,such as using  loft compound object or sweep modifier.

the path and the section of a curve road

Use RingMap to UV Map a road

RingMap

1. StEg: Set the range of edges.

2. Ring:Press the button to select edges and faces in ring mode

3. Ring Map:UV Mapping for selected faces

4. Extend:

   

   Extend

   
   

5. Add:If you also complete a part of road UVMapping and want to continue your job for remain road,you can check it . To make sure adding RingMap at your desired position,Select a vertex at beginning of the road.

6. Full:Fill the texture along the road section,that is,set U coordinate on one side to 0,another side to 1.

7. RingV: Default,the V coordinates increase along the path.If check,the direction will be change to U;

8. FlipU:Flip U coordinate

9. Backward:Make V coordinate(or U if check "VRing") decrease along the path of road. ----------------------------------------------------------------------------------

10. Patch:Use the adjacent face UV data to UV Map for selected faces

11. PatchByDir:Make UV patch along specified direction.

    

    Patch and PatchByDir

    
    

12. 2P UV:UV Mapping for selected faces along specified direction

13. 3P UV:UV Mapping for selected faces with the direction and the UV width defined by 3 points

14. FreeUV:With Apply a simple planar UVW Mapping to selected faces

15. FullUV:Apply UV Mapping with UV width defined by bounding box by selected faces

1. Show Texture:Get the diffuse texture of the current selected face and display it in the above picture region,the U and V width will also be get into the "U width" and "V width" text editor.

2. U (or V) :Get the length of the selected edge as U (or V) width. U (or V) Width:Set width of U or V.

3. Swap UV:Swap U and V coordinates for every selected UV vertex

4. Move: Move UV vertices

5. U off:Move UV vertices along U direction

6. V off:Move UV vertices along V direction

7. Rotate:Rotate UV vertices

There are some requirements for models applied ring UVMap tools,the details as below:

1. Section construct line muse be full ,or UV mapping will stop;

2. 
   

   Broken section construct line

   Right topology

   For PaveUV and PaveWall,source model is simply polygons connected by parallel edges is OK,sides number of every face can more than four,but cant be less than four;

   
   

3. PaveNoTear：The shape of section can be arbitrary ,this is not like previous tools which section is simply a line .Also,the tool can pass through non-quad polygon.
