= SUMMARY =

This article offers a method for converting a polygon’s UV coordinates from Global to Local, and vise-versa.

= MORE INFORMATION =

If you accidentally apply a texture, in the wrong mode (Local or Global), then set the mapping method and convert the surface to UV, you can use the following procedure to convert the polygon’s UV coordinates.

This procedure assumes that you need to change a 2D texture from Global to Local.


 * 1) In the 2D Texture editor, save and name the texture file.
 * 2) Delete the texture and click Cancel to exit the 2D Texture editor.
 * 3) Apply a 2D Local texture to the model.
 * 4) Once the 2D Texture editor is open, load the 2D texture file you previously saved (while in 2D Global mode).

When you preview or render the image, you will notice the UV coordinates and the mapping for the 2D Texture are retained.

This procedure is valid only when applied to the same model for which the UV was calculated. Loading the texture for a different model does not contain the UV coordinates so this procedure does not work.
