Are you sure they will release a model editor with the official tools??? I mean...editing a map is a thing...but creating a new unit is different. Besides..I'm struggling to find a way to make an Acclamator as Landing ship for the empire. I changed the model in <Company_Transport_Unit> line in the GROUNDCOMPANIESEMPIRE.XML file but the game crashed.
I've also created a new "custom" landing vessel in the TRANSPORTUNITS.XML using the Acclamator model and the properties of the standard landing craft but it didn't work.
I suspect that landing units need a spacific model. See this:
They have two specific models. How can i make a land-compatible model file for a ship that doesn't have it???
Is It possible???
