Re: Can you add more units to a mod?
 

For the missing text or description i am not sure whats up with that the models i added into my game also appear to be the same but they function properly. As for the icon try downloading the model again and replace the old one, or first go to the tga command bar and delete it and re-import. Or the last thing i can think of is the coding in the model make sure that it matches the icon file name. Hope this helps

Re: Can you add more units to a mod?
 

the parts that say missing are your text inputs like in a unit you will see something like
<Text_ID>TEXT_UNIT_V19</Text_ID>
<Encyclopedia_Unit_Class> TEXT_ENCYCLOPEDIA_CLASS_FIGHTER </Encyclopedia_Unit_Class>
and maybe some others you will need
the DAT editor DAT editor (Text) Download, Star Wars: Empire at War Tools
and here is a tutorial on what to do
DAT Editing Tutorial (Text Editing) - Everything EaW
this should take care of your (missing text)
-on the icon portion just check to make sure the icon name matches MTD= icon name in the xml
remember spelling is vital
