To make a 3D environment model look stylized, focus on adjusting key visual elements—color, texture, shape, and lighting—to create a cohesive, non-realistic artistic theme.
Simplify details: Use flat, illustrative textures instead of photorealistic ones. Exaggerate forms: Try oversize trees, angular buildings, or rounded terrain to match your style (cartoonish, whimsical, retro). Play with color: Limit your palette to bold or muted tones (e.g., pastels for dreaminess). Adjust lighting: Use soft glows or high-contrast shadows to enhance mood. Tools like Blender or Substance Painter help keep the look consistent.
For beginners, pick a clear theme (e.g., "80s sci-fi") and tweak one element at a time—start with color—to avoid overwhelming the design.
