A Novel Solution to Automate UI Reconstruction from Photoshop Design to Unity and Unreal Engine
Demo
Abstract
PSD2UMG is a comprehensive workflow and toolset designed to streamline the process of converting Photoshop (PSD) designs into user interfaces (UI) in Unity 3D and Unreal Engine. By leveraging advanced algorithms and techniques, PSD2UMG significantly reduces manual labor and increases efficiency in UI reconstruction, enabling game developers to focus more on gameplay and design aspects. This paper presents the rationale, design, and application of PSD2UMG, highlighting its benefits in various stages of the game development process.
1. Introduction
The process of reconstructing UIs from Photoshop designs in game engines such as Unity and Unreal Engine has traditionally been time-consuming and labor-intensive. PSD2UMG addresses this issue by providing an automated workflow to convert PSD files into usable UI components in these game engines. The workflow includes three main stages:
- Sensory Tree Generation
- Tree Structure Encoding
- Tree Similarity Calculation
2. Sensory Tree Generation
Sensory tree generation involves converting a PSD file into a tree structure that represents the design's hierarchical relationships. PSD2UMG's algorithm utilizes layer metadata to generate a sensory tree accurately.
3. Tree Structure Encoding
Inspired by Huffman encoding, PSD2UMG employs tree structure encoding to represent the tree structure as a string. This abstraction allows for efficient comparison of strings, specifically their prefixes, to determine relationships between nodes in the tree.
4. Tree Similarity Calculation
To evaluate the similarity between UI components, PSD2UMG introduces a tree similarity calculation formula. This metric ranges from 0 to 1, providing a quantitative basis for determining the similarity between different UI elements.
5. Application of PSD2UMG
PSD2UMG has been successfully implemented in both Unity 3D and Unreal Engine. The tool offers a simple and efficient way to reconstruct UIs from Photoshop designs, with the entire process taking less than a minute in most cases. This new workflow greatly reduces the manual labor involved in UI reconstruction and allows game developers to focus on other aspects of the development process.
6. Future Work and Extensions
Although PSD2UMG cannot be open-sourced due to company confidentiality, a technical solution will be provided for developers to follow through and realize the PSD2UMG system independently. This approach will allow the broader community to benefit from the workflow and techniques presented in PSD2UMG, fostering innovation and efficiency in the game industry ecosystem.
In conclusion, PSD2UMG presents a novel solution to automate UI reconstruction from Photoshop designs to Unity and Unreal Engine, greatly enhancing efficiency in the game development process. This innovative toolset has the potential to become an invaluable asset for developers, significantly reducing the time and effort required for UI creation and modification.
