You have to edit artdef files, for instance you look for your ship in
units.artdef, copy all element of it, paste, and change the unit name (last line of element) into your name. See my example I made a Nau from
Privateer:
Code:
<Element>
<m_Fields>
<m_Values>
<Element class="AssetObjects:ArtDefReferenceValue">
<m_ElementName text="Naval"/>
<m_RootCollectionName text="UnitFormationTypes"/>
<m_ArtDefPath text="Units.artdef"/>
<m_CollectionIsLocked>true</m_CollectionIsLocked>
<m_TemplateName text=""/>
<m_ParamName text="Formation"/>
</Element>
<Element class="AssetObjects:ArtDefReferenceValue">
<m_ElementName text=""/>
(.................................................................................................)
<m_Value text="Privateer"/>
<m_ParamName text="XrefName"/>
</Element>
</m_Values>
</m_Fields>
<m_ChildCollections/>
<m_Name text="PRIVATEER"/>
<m_AppendMergedParameterCollections>false</m_AppendMergedParameterCollections>
</Element>
</Element>
</m_ChildCollections>
<m_Name text="UNIT_NAU"/>
<m_AppendMergedParameterCollections>false</m_AppendMergedParameterCollections>
</Element>
</Element>
