Huge PCG Aquarium - UE5

The idea of this Aquarium was to build something that shows a whole reef which includes the island on top. But because it's an aquarium it contains different elements inside the water tank to make it more interesting like a statue, sunken boat and underwater structure. All shots are real-time captured inside Unreal. This aquarium was created for PLAZAMEDIA GmbH.
-----------------------------------------------
Explanation PCG: It means Procedural Content Generation, so easily spoken, with such PCGs you can populate/ fill a bigger area with something (sattered plants, full bioms, etc.) without placing everything by hand. It uses a logic one defines. It can be seen for instance as a tool for level artists but also it can generate stuff on run time if needed.
-----------------------------------------------
I created the scene from start to finish:
- blockout
- modeling the water tank
- building the island with rocks and sand tip
- creating the PCG for the main corals on rocks and Scatter PCG for foliage on the island, starfish, seaweed and corals on the bottom
- creating the spline blueprint to move fish
- water shader
- underwater caustics texture
- lighting
- also, it contains third party assets

Big Volumes (yellow): main corals on rocks
Smaller Volumes: to spawn/ remove extra coral types for artistic purpose
Pink Volumes: to remove any kind of corals (prevent clipping outside the water tank and artistic reasons)

PCG of corals spawning on rock.

Sub graph to spawn a single coral type.

Fish start with different delays for a more natural behaviour.
