-Although in both cases the material will be made "​fit" ​on the underlying surface, Bezier patches are from then on in a different texture-coordinate generation ​mode than brush faces.

With Bezier patches, which can be curved to any shape (e.g. cylindrical or spherical), this is impossible.+Although in both cases the material will be made "​fit" ​to the underlying surface, Bezier patches are then in a different ​mode regarding ​texture-coordinate generation than brush faces.
  
-As a result, the Bezier patches ​whose material is applied with the **Fit** button ​(a highly useful button with Bezier patchesputs them into a different texture-coordinate generation ​mode that is not compatible with that of brush faces: You cannot pick such Bezier patch surfaces and apply them directly to brush faces (but still to other Bezier patches), and -- more importantly -- the Scale attributes now indicate the number of repetitions of the material on the surface, rather than the number of texels per world unit as usual. The background of the Orientation attribute fields is colored in order to indicate that a Bezier patch surface has been picked that is in this special texture-coordinate generation mode.+This is because for brush facesyou could have achieved ​the same result by manipulating the Scale and Shift manually. With Bezier patches, which can be curved to any shape (e.g. cylindrical or spherical), the same mathematics cannot achieve the same effect, and thus using the **Fit** button ​on Bezier patches puts them into Fit mode that yields ​the desired result.
  
-You can "​revert"​ the behaviour ​of such a Bezier ​patches ​surface by picking the surface attributes of a brush face and right-click ​applying them to the Bezier patch in **Apply Projective** mouse-button mode.+The essence of Fit mode is that the Scale attributes now indicate the number of repetitions of the material along the surface, rather than the number of texels per world unit as usual.

 +Because of this difference, while applying the surface properties of such Bezier patches to other Bezier patches is straightforward and intuitive, applying the same attributes to brush faces is sometimes not possible without distortion. Such cases are easily fixed though by clicking and editing the affected brush surface.

 +The line “Mode: Fit” near the Orientation controls indicates that the current surface values were taken from a Bezier patch that was in Fit mode.
