Really new to BF2 modding, and so determined to find out answers to all problems before continuing .
To make a long story short, only Command Posts and turrets* spawn on my map after munging, all other objects never appear in-game, even if they are blatantly there in ZeroEditor. Making every single object built into the map with blender is becoming really frustrating, what am i doing wrong? *Turrets spawn destroyed, and require repairing by an engineer in game.

It could be that the models each odf refers to are not being found. Be sure they are in your world folders correctly.

Example, let's say you wanna use Hoth objects.
Navigate to mod tools \ assets \ worlds \ hot and copy the folders msh, odf, and effects.
Then paste them into data_mod \ worlds \ mod \

So, in your mod world folder you would now have world1, odf, msh, and effects.

During object placement, make sure you call in the odfs located in data_mod \ worlds \ odf, because they will look for those models in data_mod \ worlds \ mod \ msh

If models are not found, then nothing would appear in game (I forget if something would still appear in ZE without a model being detected)

Mod=your map ID

thanks, it works now! I pasted the whole Tatooine directory into my worlds folder before, now it works after pasting the odfs etc inside the mod directory.
