SkyCube is a tool kit & shader library for in-game HDR rendering solution, it can encode 32bits HDR file or rendering HDR ambient to 8bits RGBM to let you use HDR image in your game.
It can works with Radiance HDR(.hdr) file or generating various HDR panorama images from your scene and sample it with different glossiness for HDR IBL and blur reflection.

You can easily control rendering, convolution, format converting, and export panorama file into various format HDR skymap or cubemaps. A full custom shaders library are included for HDR IBL rendering.

Since v3.5 it includes Skycube RT 1.0, real-time HDR/LDR image base rendering solution. It renders cubemap with specular chain in real-time and cost less than standard cubemap rendering. It is a perfect solution for the case when you want use the same environment map for different glossiness objects/materials.
