Retopologize

From the Pixyz menu, choose Toolbox > Remeshing > Retopologize.

Use this feature to create a lightweight representation of a complex mesh by reducing the polygon count.

This feature is suitable for colliders, levels of detail (LODs), and devices with limited graphics power.

Note

The functions preserve animations by transferring joint assignations to the target mesh.

You can choose between two methods:

• Standard method
• Field aligned

Standard method

Create a rough mesh approximation to reach a target polygon count.

This illustration shows how you can create a collider that has a low polygon count:

This table shows the parameters for the standard method:

Parameter	Description
Quality preset	The preset of default or custom precision values. You can modify these values.
Quality value	The quality value that is associated with the quality preset. You can set a value up to 1000. For high quality and less execution time, enter 200.
Bake maps	Whether to transfer initial mesh information to texture maps: Albedo Normal Opacity Roughness Specular Metallic Ambient occlusion
Maps resolution	The size of the generated texture maps.
Is point cloud	Whether the model is a point cloud.

Field-aligned method

Create a field-aligned quad-dominant mesh (a mesh that contains mainly quadrangles) with control on the polygon count.

This remeshing process is adapted to perform these operations:

1. Create a representation that has a low polygon count compared to the initial mesh.
2. Bake information that has a high polygon count on this representation.
   For optimal baking, Pixyz strives to create triangles that are aligned with the initial geometry.

This table shows the parameters for the field-aligned method:

Parameter	Description
Strategy	Whether to target a specific polygon count or a ratio of the initial polygon count.
Use feature size	Whether to preserve mesh details that are larger than the specified size.
Feature size	The minimum size of features to preserve. The unit is the same as the unit of the selected mesh.
Bake maps	Whether to transfer initial mesh information to texture maps: Albedo Normal Opacity Roughness Specular Metallic Ambient occlusion
Maps resolution	The size of the generated texture maps.

This illustration shows the example of result with the field-aligned method:

The mesh behind is the initial mesh and has a high polygon count. The resulting mesh has a much lower polygon count.
