If your model is C4D that should work automatically, assuming that the creator saved the model correctly.
If that’s not the case or if your model is in another format, you need to use the Texture Manager to link your textures again
Window >> Texture Manager.
After that you have 2 options:
1.- Go to File >> Save project with Assets. With this you will get a new file with the textures, and even if you move all to a new computer, the textures will be linked.
or
2.- Save everything inside the content Browser to get your object with textures every time you need it.
Hope that help
Good Luck
