does anyone know how to fix the positions of dropships in sp?

Uncheck Gravity to use the arrows to move it by x, y, and z

thx but would that work for triggers, like the dropship dropping people off, say the beginning of assualt on the control room?

I think so. If not, you can reposition it the same way you resize it

how do you resize it?

Are we talking about trigger volumes? If so, you click, hold, and drag a side of the volume to resize it.

ok im not sure what it is, here is the example, the pelican for the insertion into aotcr the very beginnning, if i wanted to change where it is and where it goes how would i do that?

Not exactly sure how thats done, but it involves all the stuff under Encounters. Use Sapien to do it. Some Bungie H1 levels have banshee spawn points up in the air. I assume a script seats a biped and assignes it to an encounter, or assignes the vehicle to an encounter and then seats the biped. Navigating a particular path could involve command lists, or migration points or whatever they're called, under squads

i still cant find it

keep looking

encounters
squads
