I am new to Blender and am only using it for a few hours to quickly create and export a 3D Model in .glb format to use it in my React website project with three js.
I have applied certain Nodes in the Material of a cube, which are 'Texture Coordinate', 'Mapping', 'Gradient Texture', 'Color Ramp', Principled BSDF', and 'Material Output'. These are used to create a gradient on the surface of my cube. However, when I export my model, these Nodes are not applied and the gradient is lost, even though I clicked on 'Apply' to apply the material on this cube. I am sorry if my terms are all over the place since I am new. Nevertheless, I have attached photos to help you understand better

Thank you and cheers!!
