...hope its useful. If you need to specifying FBX export settings, look into the MAXScript Reference for "FBX Export Dialog Access" topic.if maxFilePath != "" and selection.count > 0 do
savePath = maxFilePath
selObjs = getCurrentSelection()
for obj in selObjs do
FName = savePath + obj.name + ".fbx"
exportFile FName #noPrompt selectedOnly:true
