Hello! I'm Denis. I am developing tools for creating scenic Unity terrains. As a 3D artist initially, I'm fully aware of how important the role of the tools in the development process can be. They assume all the routine, allowing you to concentrate on a creation process. It all began when I developed small scripts for personal use, and gradually it became my major activity.
Landscape creation and editing tools for Unity Game Engine
MapMagic is a platform for fast level creation and prototyping. It also supports the generation of infinite terrains. It uses a node-based interface to determine creation logic.
A tool for painting with erosion. It generates an effect of realistic hydraulic action, weathering and sediment under your mouse cursor, setting both heights and terrain textures.
Voxeland is a next generation of a cubic-style terrain, but a bit more than that: it is a subdivided and adroitly smoothed cubical structure. Terrain could be modified and updated both in editor and in-game in realtime.
Some of the other Unity plugins worth mention - all of them are free:
