Is it possible to return the beautiful vegetation and forest from the beta version? Who understands the game files? Is it possible to do this at all, maybe when the modding tools come out?
Theoretically yes, but practically probably not.
We don’t know anything about modding tools. So we don’t know, what we can do with them.
There are many differences between beta and final forests.
-Lighting and vegetation shader looks better in beta.
-Approximately 1/3 of the trees and all the small threes are deleted in final version (lot of undergrowth too)
-Some of the textures are probably lower res (not sure about that).
So modding tools would need to allow changing setting of the shaders and and place object in to the world.
Than you would need to somehow get the models and textures (which are missing or different in in final version) from beta.
Than someone would need to take those models and manually pace them in the forests. Which is very unrealistic because it would be incredibly time consuming and difficult to place them as naturally as they are in beta.
