• This blobby environment is a **high poly **blender model which can
  be decimated and used for games, or level design or for beautiful
  renders.
• Preview images were rendered in cycles but probably also possible with evee
• All the models which you can see in the render (ladder, clouds,
  platforms, stones) are modeled from scratch and included in the 3D
  files.
• There is only one (open source) HDRI included as a .exr texture
  (pink sunrise, 8k + 16k). The other (brownish) HDRI is NOT included.
• Apart from the two original .blend files (vertical horizontal
  layout) there are also .abc (allembic) .stl .fbx .obj and .glb/gltf
  files included but I recommend to use blender to export it with your own
  settings for whatever usecase you intend.

Hit me up if there are any questions.
