Questions

My test scenario is that when a gltf cube is imported, a img is used as the texture of a face of the cube,
Most of the help documents specify faceuv when creating,

If faceuv is not set during creation, I don’t know how to modify it later

for example how to modify the texture of the imported gltf cube model one face?
I found many examples of modifying faceuv in the forum,
Based on these experiences, this example is made

However, if faceuv is not set at the time of creation, the effect is error
