Hi I’ve developed a custom plug-in for blender to create specific 3D models parametrically. I now want to create cloud based 3d application that utilises blender with our plug-in on the back-end to create 3d models based on files uploaded by the users.

I made a model in blender, it has several different objects with different materials. when i export it in glb format and try to import it in a-frame the models appear and their materials also appear but the materials like glossy are just colors they are not shinning as they were in blender material preview. So, how can i import these materials properly into a-frame or are there any settings i need to change while exporting them from blender??
