Sometimes you will want to control the smoothness of a specific area of your model.
For instance, you may want to select the wing tips of the ship model and smooth them less or more than the rest of the model.
Mesh Smooth works the exact same way on a selected area of a model as it does on the entire model.
Using Mesh Smooth in combination with the Mesh Select modifier can do this fairly easily.
Mesh Select, a new modifier for your 3D Program, contains the same capability as Volume Select to select the faces, edges, and vertices of a 3D mesh.
This new feature allows you to select non-contiguous areas of a model.
Mesh Select does not allow you, however, to animate your selection- unlike the Volume Select modifier.
The new feature is also dependent upon mesh topology.
This means that if you alter the number of faces in the model somewhere in the stack before the Mesh Select modifier, you destroy your selection.
A big feature that gained with the new feature modifier is the ability to grab sub-object selections from other selection levels.
For instance, if you have vertices selected on a mesh and then switch to the Face selection level, you can use the Get Vertex Selection button to select those faces that are based on the selection of vertices.
At this point, you will use this mentioned new modifier to select the wing tips to smooth them at different levels than the rest of the body.
Apply the meshing selector modifier.
At this point you can select the wing tips one of two ways.
You can either use the Select Invert command or you can manually select the wing tips.
Which one do you think is easier? From the Edit pull down menu, choose Select Invert.
Click the More button in the Modify panel.
Choose Mesh Smooth.
From the Edit pull down menu, choose Select All to select not only the wing tips but the rest of the mesh as well.
Note that you can also exit Sub-Object level to instruct meshing selector to select the whole object.
As you can see, by using a combination of meshing selector and smoother on specific sections of the model, you can vary the levels of smoothing on a model fairly easily.
I is very recommended that you collapse the model from time to time to save on computer resource usage.
The varying levels of mesh smoothing are a result using multiple Mesh Select and Mesh Smooth modifiers on a model.
