I've got a kind of vehicle bay that's blocked off by the shield from an Imperial star destroyer. I want to keep units from getting in/out, but I want vehicles to pass through just fine. In-game, though, the shield blocks speeder bikes and fighter tanks as well as units, but it lets the UT-AT through just fine. I checked the msh and it's got a collision primitive p_-so-_shield2, which should only block soldiers and ordance, not speeders and tanks, right? There's nothing exceptional in the shield's odf that might be the problem.

How can I allow speeders and tanks to pass through? Should I change some identifier value in their own odfs?

from my experience battlefront sometimes ignores the naming convention.
i think the safest way to ensure that only vehicles can pass it is having a collision without any parameter and this line in the odf: the ut-at might get through your shield because it has a pretty whacky collsion.

Thanks; adding that to the shield odf did the trick!
