I creating a project in cycles, but I am having trouble with the materials. The materials show up fine in the material preview, but when I switch to render preview, some materials turn pink. How do I fix this? Thanks in advance!

Pink usually means that image texture path is lost (it requires re-linking). It might also be caused by wrong or missing Texture Coordinates mapping (material nodes)...
