I have a model on a scene where I can edit its material and then export everything as a glb using GLTFExporter, everything works fine, except if material.side is set to 1 (back). On the canvas it renders correctly but the exported moodel has material side set to 0 (front). This only happens with backside, frontside and doubleside works perfect.
Is this an error on GLTFExporter?
To test this, load a model, change its material side to 1 and export it.
glTF does not have an equivalent of the backside option — only frontside and doubleside. You may need to reverse the winding order of the triangles to export this.
thank you! I will look into it!
