Developing a 3D mesh deformation shader in Unreal Engine 5

Abstract

The thesis examined the Unreal Engine 5 game engine (UE5), its purpose and use cases. The goal was to develop a deformation shader system for 3D models using Unreal Engine. The development process aimed at making the system reusable and easily modifiable for various projects in the gaming and film industries.

The choice of Unreal Engine 5 for this thesis was based on the author’s familiarity with the platform and its reputation for innovative technologies widely embraced in both gaming and film industries.

Deformation is a mechanism that adds realism and dynamism to virtual worlds. It enables real-time shape transformation in objects in response to external forces, such as collisions or pressure. Deformation can enhance immersion and user engagement in the gaming environment.

The thesis resulted in the development of a functional Render Target and a vertex-based deformation shader. These tools are designed to be easily customized and integrated into various projects. Users can adjust deformation, stiffness, and durability parameters using pre-created customizable components, allowing for versatile application across different projects.
