Level Design Unity

“Gabriel & Karl have been delivering awesome tools to enable fast and easy level design directly in the Unity Editor. With ProBuilder you design, prototype and play test rapidly your levels right in Unity. With Polybrush (beta) you refine your creation by sculpting complex shapes, painting in custom lighting or coloring, and blending textures across meshes.

In Unity 2017, we added powerful visual tools like Timeline, Cinemachine, a new FBX Exporter and we are continuing on our efforts to help artists, designers and developers create and collaborate more efficiently.”
