General UV Mapping Info |
What are UV's? |
UV's
are the coordinates used to tell the computer where to place the
texture in 3D space by taking each point (vertex) of the model and
assigning it to a point on the map. Just like the X. Y, and Z
coordinates, U and V are simply points of reference to tell us where
something is in space . In the case of textures it is called Texture
space. |
What is Projection Mapping? |
A texture projection takes the image and projects it onto your geometry in a variety of ways. |
| How are they applied? |
To apply a UV Map go to Edit Polygons-> Texture-> Planar Mapping, Cylindrical Mapping, etc/ as shown below
|
Projection Mapping Types |
- Automatic Mapping
- Planar Mapping
- Cylindrical Mapping
- Spherical Mapping
- Normalize UV's
- Unitze UV's
|
| Note: All
of these projections are relatively easy to use and understand. But,
the problem is unless your geometry is a perfect cube. plane, cylinder
or sphere with equal size faces you will most likely get some
stretching and/or abnormalities. This is where you will need to use the
UV Texture editor and Photoshop to paint your faces and then project
them back onto your model. |
The UV Texture Editor |
Shows
your 3D geometry laid out as a 2D image. You then bring your 2D image
into photoshop and paint it and reimport it back into Maya and apply it
to your model. |
