The following are some of the maps I've used for Roll 20 for this campaign.
This map has a scale of 1 hex = 7m, so is more of an overview. Generated from Blender top view (and still has some Blender artefacts on it).
Scale 1 hex = 1m, some caves and waterfalls in the forest, plus an old shipping container which can be used as a nest for a large animal.
