You could add several NPC Groups with only one NPC actor in them. If I recall correctly there are several such groups. The idea is to use these different groups, each with only one NPC actor, and set each group animation sequences to different animations with different weights and times so that not every actor performs the same animation at the same time as the other actors.
I'm sure with practice you could set up elaborate scenes!
Yep already find it out with various NPC Groups and only 1 Actor ... i have to place on 4 Spots 4-5 TOS Mirror Ensign's
That are 20 single NPC Groups if i want to set everyone an special emote.
Have worked on my project "Rise of the Orion Pirates" and found a really useful issue to ... whats up with "folders" to sort his own placements?
Just an example ... with no folders you have a big list of all your placable objects and npcs ... with such sorting folders you have a better overview over all, cause you can add a "folder" - called building and move all mission critical objects in this one.
Otherwise you can add another folder and place all npc and again add another folder called ambience or something else.
