I have the same/similar problem, but I do not understand the suggested solution.
First question: Outfits & changing scenes
Currently I set up 2 different persons for one NPC. One in scene 1, another in scene 2.
I could not make it work with the outfits somehow, that's why i have 2 NPCs which are the same Character, but in different scenes. How can I make it work with the outfits only? I think using only one character with different outfits shown at different scenes would make more sense, but I could not place the NPC with a different Outfit in another scene.
Second question: Values/Conditions
I don't understand how and where I should set up the values/conditions for showing/hiding the character in the 2nd scene.
What I want:
The Maincharacter talks to the NPC in Scene1. The NPC then switches the scene from 1 to 2, but the scene itself for the Maincharacter & Player is not supposed to switch. After the Maincharacter enters scene 2, the NPC is waiting there and does something after talking to the Maincharacter. Then it returns to Scene 1 again.
What I have:
The Maincharacter talks to the NPC. In the Dialogue i set up an Action, so that after talking to the NPC, the NPC walks out of the scene and disappears (send character to position, hide character). After this, I would like the NPC to appear in the 2nd scene. But currently it is always there, no matter if the Maincharacter talked to the NPC or not. Also I did not manage to make the NPC return from scene 2 to 1. When all the actions are done and Scene 1 is entered, the NPC keeps walking away & disappearing.
It's very confusing...I'd be very happy about inputs & suggestions!
