Custom set values in Landmass Plugin for Procedural (Randomized) level/landscape creation

Hey guys, First year Game Dev Uni student here, trying to learn more about Procedural generation and working on a Uni project for evaluation. Just wondering if there is any way to randomize the variables/values that are editable, on level creation In game (Different height maps, seeds, elevation, other effects) using the Landmass Plugin. Been at it for hours trying to edit values both in the level, and outside of it (in a HUB type area), using custom events, input events, begin play/initialize events, with no luck, seems that the plugin is rather rigid in how it operates and sets its variable values? Not sure if there is a workaround or not for this. Just trying to “Set variable value” doesnt seem to want to do anything. Might have to just create a new level every time the player will want to leave the HUB area.
Any input would be greatly appreciated
Thanks.
