# Optimizing High Polygons
{% hint style="info" %}
This guide is written based on Zbrush.

### Optimizing topology mesh
Before exporting the completed high-polygon mesh, if there are too many polygons, the file can be heavy to work with topology (varies depending on computer specifications).
In such cases, it's good to reduce the **Decimation** or **Dividing** before exporting.
For this clothing, it can be seen that there are about 2 million polygons (approximately 4 million based on Tri).
If the subdivide level is still active, you can lower the level and export, or if it's not, you can optimize with Decimation before exporting.
{% hint style="warning" %}
Polygon count is defined by Tri. \
For example, Poly: 2000 = Tri: 4000.
{% endhint %}
## Export by lowering Subdivision Level
For this clothing, the subdivide level goes up to 3, and you lower it to 1 and export after deleting the higher levels.
{% hint style="info" %}
If the subdivision levels are well divided, it's convenient to use as a low-polygon mesh.
{% endhint %}
## Export with Decimation
1. Z plugin
2. Select Preprocessing
3. Choose the optimization ratio in Decimate.
1. Results of proceeding with the Decimation value set to 20% (default setting).
You can maintain the silhouette while getting an optimized high-polygon.
