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.
