Convert polygon faces to triangles or quadrangles
Convert NURBS surfaces to a polygon mesh
You
can convert a NURBS surface to a polygon mesh whether it was created in
Maya or imported into Maya from another 3D application. Trimmed
surfaces are also converted in the process.
If the NURBS surface has a texture applied to
it, this texture is assigned to the new polygonal object. The NURBS
to Polygons action bakes the NURBS UV values onto the corresponding
polygonal vertices.
To
convert NURBS to polygons
- Select
the NURBS surface and choose
Modify > Convert > NURBS to Polygons.
A polygonal representation of the surface is created at the same
position as the NURBS surface.
If you convert the NURBS surface with construction
history on, you can edit the NURBS surface and the polygonal surface
will be recreated to match.
Notes
- If
a NURBS surface is converted into a polygonal object using the NURBS To
Polygons feature, and if the history of the NURBS surface is modified to
generate an invalid (Null) NURBS surface, the following warning
message displays:
Warning: nurbsTesselate1
(Nurbs Tesselate Node): invalid input NURBS surface.
and the NURBS To Polygons operation will not
be successfully performed. The resulting polygonal object will continue
to be the last valid (computed) polygonal surface that was visible.
- In
some cases when converting multiple NURBS patches to a single polygonal
mesh you may notice strange shading effects on the mesh. This is because
of the normals. To correct the shading due to normals, see
Fill holes in a polygon mesh.
- NURBS
to polygon conversion does not take the Fix Texture Warp attribute
(which adjusts a texture’s UV parameters so the texture does not rely
on a NURBS object's UV parameterization) into account.
