How can I use actor.getProperty().setNormalTexture(normalTex)

Web

hello,everyone!I want to add normal and rough textures to my OBJ model, but these two lines of code
actor.getProperty().setNormalTexture(normalTex);
actor.getProperty().setRoughnessTexture(roughnessTex);
don’t seem to work. Can anyone tell me specifically how to use them?

That should be correct. Are you creating the textures correctly, and are you using WebGPU or WebGL?

I referred to the official example to complete the texture mapping, and I am not sure if the following code is used correctly

createTexture(src) {
      const _img = new Image();
      _img.crossOrigin = "Anonymous";
      _img.src = src;
      const _tex = vtkTexture.newInstance();
      _img.onload = () => {
        _tex.setInterpolate(true);
        _tex.setEdgeClamp(true);
        _tex.setImage(_img);
      };
      return _tex;
    },
const normalTex  = this.createTexture(this.fileContents.img["own/Leather037_1K-JPG_NormalDX.jpg"]);
actor.getProperty().setNormalTexture(normalTex);

actor.addTexture(texture); this code is ok.Only “setNormalTexture”，this type of interface does not work

I would also check to make sure you are using the correct WebGPU renderer. I think those textures only work under WebGPU; I don’t think they work under WebGL.
