GLTF blending issue

I need a suggestion is there a way that when i download the gltf i get the maps with additive blending or multiply blending?

These blending modes are not defined by the glTF format. If you’re loading a glTF model in three.js, you’d need to modify the material (usually THREE.MeshStandardMaterial) after loading, to set the blending mode you want.

what i am doing is i am taking the whole scene and using gltfExporter so that i get everything all the material but i am not able to get the blending

It will not be possible to export those blending modes to glTF, sorry; they do not exist in the format. If you need all three.js features represented then it would be necessary to use the three.js JSON format (object.toJSON()). To see which features GLTFExporter can export to glTF, see…

… and the material extensions later in the file.
