POLYONE – Modular World Builder (Pro) is a professional Unity Editor tool for fast, manual‑first modular world building with advanced workflows and production‑ready tools.POLYONE – Modular World Builder (Pro) is a Unity Editor tool created to streamline manual modular world building for production‑scale projects.While maintaining the same manual‑first philosophy as the Lite version, the Pro edition expands the workflow with advanced placement tools, controlled randomization, and multi‑prefab collection support, allowing environment artists and level designers to build larger and more complex scenes efficiently.Instead of relying on heavy procedural systems, POLYONE (Pro) focuses on artist‑ and designer‑driven placement. Users can place or paint prefabs directly into the scene with clear visual feedback, precise control, and optimized Undo handling suited for real production workflows.Included Modular Terrain Assets (Pro)In addition to the tool itself, the Pro package includes a ready‑to‑use modular terrain asset library, allowing users to start building complete environments immediately without relying on external asset packs.Included models:10 × Cliffs18 × Hills12 × Mountains15 × Terrain pieces2 × Rivers1 x SkyboxAll included models are:Fully modular and reusableDesigned to work seamlessly with the Place and Paint workflowsSuitable for stylized environments and prototypingCompatible with Built‑in Render Pipeline, URP, and HDRPThese assets are intended to support rapid scene blockout, terrain shaping, and environment detailing directly inside the Pro workflow.The Pro version is designed for medium to large scenes, scalable environments, and professional use cases, while maintaining clean hierarchy organization and predictable results throughout the world‑building process.Contact me for support.
