What is Rapid Environment Editor?

Rapid Environment Editor (REE) is a powerful yet easy-to-use 3D modeling application for speedily creating indoor and outdoor environments. Whether you need to mock up a simple interior space, design expansive urban cityscapes, or anything in between, REE provides all the necessary tools.

At its core, REE lets you construct environments out of basic 3D shapes like cubes, spheres, cylinders, planes, and more. You can stretch, rotate, duplicate, and boolean these forms to craft intricate structures and layouts. REE also comes equipped with advanced features like terrain and foliage generators to instantly create natural landscape elements like hills, forests, rivers, and rocks.

An intuitive interface allows you to drag-and-drop models into your scenes and apply customizable materials like wood, metal, brick, and other textures. Dynamic lighting and global illumination enable you to set moods and atmospheres with ease. You can even import assets from 3D warehouses to embellish your environments.

Whether you’re an architect visualizing a building concept, an urban planner designing future cities, a game developer crafting 3D levels, or a graphic artist generating scene backdrops, REE provides the versatility and power to bring all your ideas to life quickly and beautifully.
