Preserve UVs

Preserve Map Channels is a convenient way of making corrections to your UV coordinates within the viewport, instead of needing to use the Unwrap UVW modifier. When tweaking a model after its texture map has been altered, you can more conveniently make minor changes to the vertices of your model so the texture fits better.

The Preserve UVs check box (Figure 3.22) is new to Editable Poly and Edit Poly. When this check box is enabled, a vertex or other sub-object will "swim" through the UV coordinates, as if the texture were being held in place while the model is further deformed.

Save your work prior to using this method! If vertices are moved too far, you can cause damage to the texture coordinates. For example, if a vertex of a four-sided polygon is placed within a triangle shape, further movements will damage the mapping coordinates (Figure 3.23).

If you have several mapping channels on your model, you can pick which ones are preserved with the Preserve Map Channels dialog, accessed by clicking on the Settings button (Figure 3.24).
