Is DLC possible with visionaire?

I was just wondering this: Is it possible to somehow set game that way so in the future we can make some sort of DLC or expansion for existing game, so without need to redownload "base" game, just update existing files/scenes etc. of the game? I did not find the way to do this, but maybe there is solution in some heavy scripting? Or not? I just wanna know if it is possible. Thank you in advance.

You could create episodes I suppose. There's a function that let's you replace/load in a different vis file.

As for manipulating the actual game, it's unrecommended as the save files will be lacking data & will likely generate random bugs when loading from them. Why it's recommended you try to make the game as finished & bug ready as possible before officially releasing/selling it.

Thanks for answering. I know all about saves and thier lack of info from version to version. And ofc I know that we may create episodes. But I never liked game that has seperate episodes. I was thinking only like really proper "updates" or expansions alike some AAA games like fallout, diablo etc... where we may download expansion or DLC and still read old saves. I don't think I'll bother to much with this cause it is really not essential for my game. I just thought that would be nice to have way to do this. Maybe in some of future versions of engine? 

Maybe. There's some methods to make VS less likely to have save game issues later on.

1. create a bunch of surplus conditions & values to rename & use later on. If they exist then they exist in the save data too by ID rather than name. It's usually new conditions & values that cause the issues as far as I can tell.

2. add an action part inside of an at begin of scene action for every scene that sets the background music.

3. same again, but add an action part that sets the lightmap.

I think that's about it. There's no guarantees that this will solve old save game data issues, but it might solve some of them.
