Blender covers the entire 3D pipeline in one free package, which is why so much web 3D starts there. Its native glTF and GLB export means a model can go from Blender straight to the browser with its PBR materials (base colour, roughness, metallic, normal) intact.
The web-relevant workflow is usually: import or model the object, assign PBR materials, then export a GLB with Draco compression for the web and Android, plus a USDZ for iOS AR. Legacy FBX files are commonly brought into Blender first and re-exported as GLB.
Once the files exist, PausAR Viewer takes over on the WordPress side. Drop the Elementor widget in, upload your Blender exports, and the plugin renders the model and handles Web AR, no coding.
