Before we go into the details of this article lets have a look at some of the important points about 3D modeling.

3D modeling or 3D designing is a process of creating a computer based graphic with 3Dimensional surfaces with the help of some special 3 D modeling software. Before we move on to more of its details let’s take a quick look at the difference between 2Dimensional design and a 3Dimensional design.

2Dimensional computer graphic is once which is designed using only two axes these are:

  1. x-axis
  2. y-axis

The designed graphics are made keeping in mind the x and y-axis only.



  • x-axis
  • y-axis
  • z-axis
  • Now comes "what is UV?"  why do we use the term “UV” in Maya for unwrapping any 3D object created in Maya. The reason behind this is that this process projects a texture map onto a 3Dimentional model created in Maya. Here the letter “U” and “V” denote the axis of the 2Dimentional texture. Since the axis x,y,z is already used to denote the axis of the 3Dimentional model.

    There are some different types of UV Mapping in Maya for a different type of objects. In this article, we are going to discuss planar mapping for plane surfaces.

    Planar UV Mapping:  Planar mapping is done for objects which are a flat surface.

    Here we are going to discuss how we can apply the texture using planar mapping with a stepwise process.

    1. Select the object and apply checker on to it. Maya modeling
    2. Right-click on the object and select, assign a new material. Maya modeling
    3. Select a material like a lambert or blinn. Maya modeling
    4. Go to the attribute editor and click the square checked base to apply checker on it. Maya modeling
    5. Select the checker option from creating Render Node Window. Maya modeling
    6. You will see the object will be filled by checkered texture but the checker is not perfectly squared and are also blurred. Maya modeling
    7. To make it look perfect we are going to select the face and apply planar mapping on the object.
    8. Go to object, right click and select the face option.
    9. Now click the face to make the changes on. Maya modeling



    10. Goto creates UV in the polygons section and selects the small square box beside the planar mapping.

    11. Here in the planar mapping option select Fit Projection to → Best Plane and click Project.

    12. Small checkers will be seen which are not blurry like the ones earlier but still are not perfect squares.

    13. Now go to Edit UV → select UV texture editor.

    14. A UV texture editor window appears from here we can make some changes to get the perfect checker on the plane.
    15. Now using the scaling tool adjust the UV so that we get the perfect square on the plane selected.

    16. Now we can see the difference and this checkered texture can be replaced by non-checkered ones or some image texture

    17. Now repeat the process for the remaining faces until you get the perfect object view.
