I am trying to import a large single fbx file with thousand of multiple meshes. All the import process goes good but all the models shows invalid lightmap setting except the first one. Now I know to fixed it, i have to generate a new UV set or to change the lightmap co-ordinates to 0 but there are thousand of meshes so is there a way to set the lightmap co-ordinate for all the meshes instead of going through each one of them manually.
Thanks.
