Load photogrammetry data ,but the material is lost

Dear everyone,
I load photogrammetry data via 3d tiles type ,but the material is lost. Has any suggestions? Thank you very much.

Hello,

When you say the material is lost, is it simply rendering a white or checkerboard material, or is it not rendering at all?

If you are able to send me the data you’re experiencing this issue with, I can also take a look and see if I can figure out what is going wrong.
