Applying Angle for Smoothing Meshes

In the 3D virtual world, each model is composed of numerous mesh faces, also known as polygons. One model can be composed of many different number of faces. The more faces, the smoother the model and the more computing resources it consumes.

Character Creator introduces the Auto Smooth feature for the surfaces of hair, accessories, and clothes without increasing the number of polygons. The edges of two adjacent faces can be smoothed when the physical angle they form is less than the one you defined by the normals.

1. Select a custom created hair, accessory or cloth (in OBJ format) you wish to smooth (in this case, a pair of pants).
   
2. Click the up / down arrow to increase / decrease the value of the angle. You may also directly key in the value.
3. Click the Apply Angle button.
4. (Optional) If smoothing does not seem to work, then enable the Merge Identical Points box and click Auto Smooth again.
   
   Note

   Sometimes the meshes of the imported model look like one-piece, but they are actually composed of separated faces or vertices. The Merge Identical Points feature welds adjacent faces and vertices together so that they become a unified surface. This helps to correctly represent the normal and texture alignments, which will respond correctly to the Apply Angle command.
