To sculpt humanoid 3D models for games, start by blocking basic shapes in tools like Blender or ZBrush to set proportions, then refine details while optimizing polygon counts for real-time performance.
After blocking, use sculpting brushes to add anatomical details (e.g., muscles, facial features). Next, retopologize to create a clean, low-poly mesh—critical for game performance, as high-poly models cause lag. Then texture with software like Substance Painter to add skin, clothing, or accessories that match the game’s art style.
For beginners, use free base mesh templates first—this lets you focus on refining details instead of building proportions from scratch, making the process easier to learn.
