The First Journey
A real-time scene I created based on the illustration from the children book The First Journey by Phung Nguyen Quang and Huynh Kim Lien. All the materials used are procedurally generated to most extend, with many being 100% procedural. Thanks to that, the textures are flexible and adjustable even in the engine itself.

Researching
The project is started with researching and comparing different methods of achieving the same visual effect to find one that is the most sufficient.
In case of procedural texturing in Substance Designer, problems are mostly about the aesthetic, i.e. how to achieve the closet result to the illustration. For example, figuring out how to procedurally map the texture onto the mesh correctly, to achieve the desire wave pattern or dotted seam for an alpha mask.
On the order hand, the problems in Unreal Engine's shaders are more technical, i.e. how to simultinously achieve all the visual goals without conflicting with each other.
Textures Pack - Substance Designer
First, all the style's signature elements are made into Source Graph. These were used later on as foundation for the actual textures, making the textures pack optimal and easily expandable.
All graphs can be driven by both randomized or specific custom inputs. On the right is examples of procedural masking for the algae.
Shaders - Unreal Engine 4
After that, multiple shaders are created in Unreal Engine 4 to further support translating the illustration into 3D. Down below are the shader graphs for water (using @MaxMakesGames's ripple technique) and algae.
Scene Compositing
This is a really straight forward process with primitive assets.
