The process for setting up a multi-person gesture is the same as that for Gestures - Single Person Animation, except;
Enable the trigger in the Avatar Effect Script. Set the trigger radius to 4.
Users can initiate a two person gesture inworld with a visible circle around them.
Attach the Avatar Multi Animation Effect Script instead of the Avatar Effect Script;
Clip A / Clip B
Drag the animation takes from the fbx files for each of your two characters into these fields.
Clip A will play on the initiator of the gesture. Clip B will play on the guest.
Distance Apart
You can offset the characters here if you have not already defined the offset in via the root nodes of your models in your animation editing tool.
Fix Avatar Heights
If your gesture involves both characters engaging in a very prceise interaction, for instance shaking hands, you can align them using Fix Avatar Heights. Gestures played by tall and short avatars may not look correct otherwise.
Start Time
You can delay the initiation of the animations.
IK Targets
You can select one or more nodes on the avatars and impose an IK through the animation to correct for discrepancies in avatar sizes and shapes.
See Gestures - Single Person Animation for further information on FBX settings and exporting gestures.
