I would like to now if it is possible to create some 3D models and put it on a map.

A great example is the known and nice 1v1 Map Theta Passage.

That is a reclaimable rock

It should be possible to make 3D models. With scripting you can also make sure that the models cant be reclaimed if I'm right.

Correct me if I'm wrong, it's been too long since I've been mapping supcom maps.

You are indeed correct.

Thanks.
