Zmodeler

ZModeler (short for Zanoza Modeler) is a 3D modelling application developed by Oleg Melashenko, designed primarily for creating and modifying models for use in video games. Initially released in the early 2000s, ZModeler has become a popular tool among modders and game developers for building custom vehicles, characters, and other in-game assets.

ZModeler is particularly known for its support of game-specific formats and workflows, making it a preferred choice for modding titles such as the Grand Theft Auto series, Euro Truck Simulator, American Truck Simulator, 18 Wheels of Steel, and Midtown Madness, among others. It supports various import/export filters tailored to the requirements of these games.

Later versions, including ZModeler3, introduced enhanced features like better texture management, shader support, real-time rendering previews, and compatibility with more modern file types. ZModeler continues to be actively developed, with updates focusing on expanded support for newer game engines and user-requested features.

Although not as widely used in general-purpose 3D modeling as tools like Blender or 3ds Max, ZModeler maintains a niche user base due to its specialized toolset and ease of integration with modding pipelines for specific simulation and open-world games.
