Convert PBR to Standard material

I have a glb model exported from blender which is made up of multiple smaller meshes. all meshes have the same material with a texture(proper uv mapping).

when i load this into browser it has a PBR material with the texture in the albedo property. How to convert that material to standard shader and use the same texture in its diffuse property.

Do i need some settings in blender or do i change it somehow in babylon

GLB uses PBR Materials by default so if you want to change to standard you’ll have to do it in Babylon
