Is it possible to let the driods (and rep) go in orderedand structured groups? (Like in the battle of christophsis/The clone wars). If, how could I do that ?

no, thats not possible. you can only make paths so that the ai runs on them but they will still rund along the paths and leave them if they attack enemys.

I guessed that, but I´ll do a few tests
Edit: I did the tests and it won´t work , but I´ve got another question, why deos my clone commander look different when he´s close up, even if I didn´t change anything ? Close up it´s the blue arc, i think and far away it´s the normal Marine commander.

It means you didn't change the lowrez geometry the model uses. So from far away it would look different.

But I didn´tchange aything and it´s a new map, so it should all be the same ??!

Sounds like the 1.3 patch sides. I think the low rez still uses the old stock model.

yes, i think it does.

Yeah, I always wondered about that. I just figured it was meh computer.

Good, so I´m not the only one
