The texture of OBJ missed asset ID 652702

Dear officer
I uploaded a obj file in ION asset with its mtl file and the picture of the texture. It looks nice and I put it the right location.
However, when I add the file into my UE4, the texture of the photogrammeter missed.
The asset ID 651514.
Could you please tell me how can I get the colored model?
Thank you so much.

For reference, here’s how it looks in CesiumJS:

And here’s how it looks in Cesium for Unreal:

We’re looking into this and will get back to you soon.
