Unreal Engine: Ultra-Realism Park Conversion

PROJECT: Convert My 3D Park Video Into an Ultra-Realistic Walkable Unreal Engine Environment

I have a short 5-second 360 cinematic video of a 3D-rendered park environment that I want converted into a fully explorable, ultra-realistic real-time 3D experience inside Unreal Engine.

The final result needs to feel as realistic and immersive as possible — with physically accurate materials, lighting, textures, vegetation, and environmental detail throughout the park.

The environment must allow me to freely walk around using keyboard and mouse controls (WASD movement + mouse-look) similar to a modern first-person Unreal Engine environment.

IMPORTANT:
This is NOT intended to look like a “floating NeRF scan” or blurry point cloud. I want the final result to feel like a polished next-generation environment using proper Unreal Engine materials and rendering techniques.

The workflow can involve:

* Gaussian Splatting
* NeRF reconstruction
* Luma AI
* Postshot
* Nerfstudio
* Photogrammetry workflows
* Manual environment rebuilding
* Hybrid reconstruction + Unreal cleanup

I am happy for the freelancer to:

* reconstruct the environment from the video
* rebuild sections manually if required
* replace vegetation/materials with high-quality realistic assets
* improve realism beyond the original render where needed

The final environment should include:

* Ultra-realistic park materials
* Realistic grass, trees, pathways, concrete, water, etc.
* Proper lighting and shadows
* High-quality textures
* Real-time rendering inside Unreal Engine 5
* First-person walk-through controls
* Mouse-look camera movement
* Smooth navigation
* Optimised performance

Preferred Unreal Engine features:

* Nanite
* Lumen
* Megascans/Quixel assets
* Realistic foliage systems
* Cinematic quality rendering

Deliverables:

* Unreal Engine 5 project files
* Fully walkable environment
* Executable/demo build
* Exported scene files
* Instructions for opening/running the project
* Any plugins/workflows used

Please provide:

* Examples of similar work
* Experience with Unreal Engine 5 environments
* Experience with Gaussian Splatting / NeRF workflows
* Your recommended workflow for achieving maximum realism
* Estimated timeline and pricing

NOTE:
I currently only have the rendered video of the park environment — I do not currently have the original 3D model files.
