# 3D Content

- [Tags](https://docs.variant3d.com/3d-content/tags.md): By tagging materials and meshes in a file, we can request any possible combination of 3D assets from the Variant API.
- [Tagging Objects & Groups](https://docs.variant3d.com/3d-content/tagging-meshes.md): Tagging objects so they can be changed when product variants are generated
- [Tagging Materials](https://docs.variant3d.com/3d-content/tagging-materials.md): Tag materials to make them available to be applied to meshes.
- [Using Swatches](https://docs.variant3d.com/3d-content/using-swatches.md): Swatches prevent your 3D editor's export process from removing materials you want to upload, but haven't used on the model.
- [3D Model Delivery Requirements](https://docs.variant3d.com/3d-content/3d-model-delivery-requirements.md): To be re-processed across a range of platforms with differing features, your model needs to meet these requirements.
