This kit enables you to easily create skies for games or interactive web content. When a sky or environment texture needs to be displayed in real time, it is usually implemented as a cube map because of the performance advantages. Unfortunately, rendering directly to a cube map is not presently a feature of Cycles. Fortunately, with this kit you can easily create a cube map using any render engine in Blender, or from an existing environment map.

This kit uses two .blend files to create a cube map: a "Cube Cam" for rendering the tiles of your cube map, and a "Cube Map Compositor" for combining your six cube map tiles into one final image in the correct layout.

There are sample files included as well, so you can test it out right away, and better understand how it works. Try loading up the sample environment and rendering it!
Documentation is included inside the .blend files.
There is also an example .html file demonstrating a cube map applied in an interactive environment, created using Blend4Web.
