Module 2

If you would like to purchase an asset on a third-party asset store, you will find that most marketplaces offer free and premium assets. When using third party asset stores, be aware of asset compatibility. To avoid the need to adjust the asset’s mesh, look for assets with a garment mesh of A-pose or T-pose (module 4 covers A-pose vs T-pose). Assets may need modification in order to best perform in Lens Studio and dynamically deform to the Body Mesh. You might need to adjust the asset's polycount and mesh to name a few. When adjusting an asset's polycount, keeping it under 50,000 triangles will ensure that your model displays smoothly across the widest variety of devices. When adjusting Body Mesh, please refer to Lens Studio’s reference model. 

NOTE: always check usage rights of assets that you purchase and be aware that purchased assets may need some modification to reduce file size. Lens Studio recommends keeping assets under 2 MB per model.

If you want to create your own garment/accessory, but you do not yet know how to create 3D assets, check out learning materials of software we shared in Module 1. You can find tutorials on YouTube or documentation by searching Google. You can spend as much or as little time on creating your asset. As you dive into asset creation, remember that you will need to create an External Body Mesh. To do so, use a reference model provided by Snapchat. Try to keep your 3D model under or around 2MB per model. If you are interested in having more than one garment or accessory in your Lens, consider optimizing asset size. While Lens Studio doesn’t have a strict asset size limit, the maximum Lens size is 8MB. For better performance on lower power devices, we recommend lenses less than 4MB.

Once you are familiar with how to create a Lens, you can spend more time in 3D creation tools and make more complex 3D garments/accessories for your future Lens.
