My basic problem is that blender does not store normals while exporting to x3d. If anyone could help me on how normal interpolator is applied or which is the right processing path for a model to be exported to x3d, it would be nice 🙂
I do not know blender, so I can not help you there but there should be a way to export normals explicitly from blender, otherwise it seems lack a lacking feature.
Did you take a look at the NormalInterpolator example in the directory H3DAPI/examples/All of your installation.
