Polycount

Polycount is the number of individual polygons that make up your asset’s geometry. Almost all 3D apps allow a way to find the total number of polygons in your asset.

Make sure your total polygons are fewer than 250k. This can be challenging for certain use cases where the shapes are organic or complex. Make sure to reduce the poly count of the assets for best performance.

Good to know: Sometimes it's easy to confuse Polycount with Tricount. Generally, Tricount is twice as much as Polycount. If your software shows Tricount only, limit them to 500k

Make sure you are not using any plugins to create procedural geometry. If your 3D app allows you to bake the procedurally generated meshes you can use it.
