hi. I am trying to use a google terrain map in unity 3D. I am using sketchup pro and when I export the terrain map to fbx file,in unity the terrain is shown only in gray-scale and no texture is being imported.while exporting from sketchup to fbx,the textures are being stored as several JPG files in an specific folder but I cannot use them. does anyone know how can I solve this problem?
You need to copy the JPG files into a /Textures subfolder in your Unity project before you import the FBX file. Then Unity should pick them up and assign them automatically when you import the FBX.
This is detailed in the manual and in previous answers on this site.
