Thank a lot @Noctro,
a few more questions, but then i think i got it :)
Ok i understand that GM Mode is a tool for Pen and Paper (very cool) and not an editor to script things, it's more to do things on the fly, prepare something you can use, but have to actively do as a Dungeon Master and lead your party, moderate their actions and act as the world.
I'm familiar with that, the more i do with the GM Mode, the more i understand what i can and should do do start a session.
I recently figured out, that you can add more scenes than Pins, Pins just are Travelspots.
I now managed my first Campaing this way:
choosed a Map, set some Pins with Levels, created folders for each Pin with multiple Vignettes and Scenes in that folder.
So if the group arrives at Village X, there is the starting Scene and Vignette i use to ntroduce the scene, but i have several areas/ scenes in the vignettes and scenes folder of Village X to play with. For example the Tavern as an indoor level, the cellar of that Tavern or the Graveyard at the Villages Border etc... and these Scenes aren't pinned to the overworld, but are available from storytelling or even Vignettes i prepared.
great thing so, many possibilitities and even making a quick encounter on the fly to react on players behavior is possible, if one becomes used to it and have for example some general NPC stored/ exported and some genereous Vignettes for random encounters prepared.
But it's still better to keep it linear, but thats totally ok for me.
So now what's important to me!
I found adittional scenes in the Workshop, some unofficially released scenes and Goblins and some Undeads as NPC's
Cool things, want more of that.
And i dowloaded a short "Adventure", what taes place in a Tomb after entering it from a graveyard.
So this is where it comes to scripted Adventures and playermade 3d levels if i'm right.
What is that Editor to create own 3d Levels, is that the tool to create scripted Adventures like the one i tried?
Where is this, how do i start this Editor for 3d Levels?
