1. Install the add-on
In Blender, open Edit → Preferences → Add-ons, choose Install, select ignlab_blender_exporter.py, and enable IGNLab Web GLB Exporter.
A BLEND file is a working project. GLB is the portable delivery file your browser needs. The IGNLab add-on performs that export locally and packages supported textures, materials and animation into one file.
In Blender, open Edit → Preferences → Add-ons, choose Install, select ignlab_blender_exporter.py, and enable IGNLab Web GLB Exporter.
Use Principled BSDF materials and make sure image textures are linked correctly. Save the BLEND file before exporting.
In the 3D View, open the sidebar with N, select IGNLab, then choose Export web-ready GLB. You can also use File → Export → IGNLab web-ready GLB.
Open the exported GLB in IGNLab 3D. The browser checks its structure, textures and web readiness before you optimize or download it.
