Subdivide Modifier

Subdivide Modifier

The Subdivide modifier is a modifier that divides the current face into quarters while simultaneously smoothing out bends.

note

The Smoothing Groups property of the Face Element Group increases the actual number of faces, rather than just making it look like the faces are connected.

How to Use​

  1. Press the Add Modifier button. Modifier Add Button

  2. Select the Subdivide modifier. Subdivide Modifier Properties

  3. In the Subdivision Level properties, select the Button for the desired step. Subdivide Modifier Level

    caution

    Since this will divide the entire face into 4 parts per step, it is recommended that you start with a lower step, as the number of steps in the Subdivision Level property can cause optimization issues with 3D objects due to the large number of steps, as well as momentary editor slowdowns.

  4. faces are added and bends are smoothed out. Subdivide Modifier Result

Property for the Subdivide Level.

Subdivide Modifier Level

For each step, the number of faces is quadrupled and the bends are smoothed.

Interpolation​

None​

Edge Only​

This property determines the bend without distinguishing between corners and edges.

As a result, all vertices are smoothly represented.

Edge And Corner​

This property determines the bend by distinguishing between vertices and edges.

UV Interpolation​

This property sets the bending method for stretched UVs.

note

This does not work if the UV is not unfolded.

info

Even if the UV is not stretched, it will have automatically generated UV texture coordinates based on the object's spatial coordinates, normal orientation.

The image below is an example of how the UV changes based on each property.

Auto Smoothing Group​

A property that automatically applies a Smoothing Group to faces added by the Subdivision Level, making the surface appear smoother.

tip

Since increasing the value of Subdivision Level results in more polygons, it is a good idea to optimize by looking at the representation level with the Auto Smoothing Group property enabled and increasing the value of Subdivision Level.
