Hello, what object should be taken to add vaissaux (destroyer with hangar ect ...) on a map on earth?

Are you referring to the imperial star destroyer? If you want all of it in a land map you should follow the instructions I gave in this topic but select only the star destroyer objects.

sorry but I do not quite understand me what I want is to know or is the object (for example: asset / world /...) I would like to know the same ca to add space

you have to take the models textures and odfs from their respective folder in "BF2_ModTools\space_template\Worlds\@#$"

I'm not sure I understand what you want. Do you want the imperial star destroyer in your land map? The star destroyer is not a single object; it is in fact made of many objects. To put the star destroyer in your own map you need to copy all of the files located in the location DarthDuck gave and put them in "data_XXX/Worlds/XXX" and in their respective folders. It is best if you do the copying first and then load a space world (you could make your own just for getting the destroyer data) and following the instructions I gave in the previous reply.

I'm sorry if I sound mean, I'm not trying to be; I'm just trying to make more sense.

All that seems to me very complicated but I'll try thank you very much!
