− - [How to make a 3D model look like it's standing somewhere](https://vectreal.com/news-room/3d-model-shadows-and-lighting.md): A 3D model without a shadow looks like it's floating. In the Vectreal Publisher you ground it with two switches, a shadow cast by a light and a darker one where it touches the floor, then pick one of 15 lighting presets and blur it into a soft background if you like. No 3D background needed.− - [How to open a GLB file](https://vectreal.com/news-room/how-to-open-a-glb-file.md): To open a GLB file, drag it into a free browser viewer such as the Vectreal converter, Babylon.js Sandbox or the Khronos glTF Sample Viewer. Nothing to install. On a current Mac, Preview opens it too. On Windows, Microsoft's 3D Viewer has left the Store, so use a browser viewer or Blender. On an iPhone, convert it to USDZ first.− - [How to Add a 3D Model to Any Website - The Complete Options Map](https://vectreal.com/news-room/how-to-add-3d-model-to-website.md): Four paths for getting an interactive 3D model live on a web page - from no-code publisher to React component to full engine - with a decision matrix that finds your fit.+ - [Lighting](https://vectreal.com/docs/guides/lighting.md): Lighting setups, the environment, key, fill and rim lights, the ground shadow, and the background.+ - [How to get a 3D model of your product](https://vectreal.com/news-room/how-to-get-a-3d-model-of-your-product.md): There are six routes: scan it with a phone, hire a 3D artist, convert the CAD files it was designed in, license an existing model, generate one from photos with AI, or use a marketplace's own program. Which one fits depends on the product's surface, whether CAD files exist and how exact the model has to be. Whichever you pick, ask for a GLB, the file web viewers load.+ - [Publish 3D models from your AI agent](https://vectreal.com/news-room/publish-3d-models-from-your-ai-agent.md): The Vectreal MCP server lets the coding agent you already work with, in Claude Code, Cursor or VS Code, upload a GLB, set its lighting and shadows, publish it compressed and hand back the embed code. It runs on your machine through the Vectreal CLI, and you sign in once in the browser and choose what the agent may do.+ - [How to add hotspots to a 3D model](https://vectreal.com/news-room/add-hotspots-to-a-3d-model.md): A hotspot marks a detail on a 3D model that people would otherwise miss. When a visitor clicks it, the camera moves to a view you set for that detail and a card opens with your text and, if you want one, a link. In the Vectreal Publisher you place markers by clicking the model and number them in the order you'd like them visited.+ - [How to make a 3D model look like it's standing somewhere](https://vectreal.com/news-room/3d-model-shadows-and-lighting.md): A 3D model without a shadow looks like it's floating. In the Vectreal Publisher every one of the eight lighting setups comes with Ground shadow on, a floor that catches the shadow its lights cast, so you pick the light that suits the product and blur the environment into a soft background if you like. No 3D background needed.+ - [How to open a GLB file on Windows, Mac and iPhone](https://vectreal.com/news-room/how-to-open-a-glb-file.md): To open a GLB file, drag it into a free browser viewer such as the Vectreal converter, Babylon.js Sandbox or the Khronos glTF Sample Viewer.

With a few lines of HTML, Google's model-viewer shows a GLB you host yourself, and in a React app a component such as @vctrl/viewer or React Three Fiber does it. On Shopify, upload a GLB as product media and it appears in the product
