Hi thank you for the verification. I can open the model with cad assist, and I checked the .gltf file, the texture directory seems to be correct.
I can think of two ways to solve this problem.
1.I tried loading the models only with vtkGLTFReader, maybe I can then apply textures to this model to achieve the same result.
2.verify if the models are downloaded correctly using another library. I’ll try F3D and see if it loads textures.
