The recent announcement of Hunter x Hunter: Nen Impact has generated excitement not only among manga fans but also among developers observing its technical architecture. This 3 vs 3 fighting title, developed in Unity with assets modeled in Autodesk 3ds Max, faces the challenge of delivering a classic anime aesthetic without sacrificing frame rate. The goal is to achieve stable 60 FPS in a competitive environment, where every frame counts for combo precision and input response.
Modeling in 3ds Max and optimization for real-time 🎮
The pipeline begins in 3ds Max, where characters are modeled with clean topology and contained polygons to facilitate real-time deformation. As a fighting game, animations require fast transitions without heavy interpolations. Assets are exported in FBX format with optimized meshes and flat UVs for light maps. In Unity, toon-style shaders with flat shading and silhouette edges are applied, achieving the anime look without using complex textures. To maintain 60 FPS in 3v3 matches, manual Level of Detail (LOD) usage is prioritized, and dynamic lighting in stages is avoided, using baked light grids from 3ds Max.
Visual clarity and competitive performance ⚡
The technical key of Nen Impact lies in visual clarity. In fighting games, readability of attacks and hitboxes is critical. Developers have opted for simple particles and solid colors for special effects, reducing the load on Unity's particle system. Additionally, an aggressive culling system is implemented for characters off the camera plane, and the frame rate is synchronized with the physics engine in FixedUpdate mode. This combination allows the often costly offline anime aesthetic to translate into stable competitive performance, demonstrating that Unity can compete in the traditional fighting genre.
How was the technical pipeline optimized in Unity to faithfully replicate the movements and Nen abilities of Hunter x Hunter: Nen Impact without compromising real-time performance?
