SkyCube v3.0 : HDR Panorama Converting / Rendering Tools & Shader Libs

April 14, 2015

Ver30a

SkyCube is a tool kit & shader library for generating HDR panorama images (skybox, crosses or cubemap) from your scene or imported HDR file and transfer them to HDR IBL diffuse and HDR specular IBL cubemaps for image-based lighting in Unity. It gives you a solution to use 8bits texture which encode HDR information(RGBM) to allow it be saved and simulate 32bits HDR result efficiency in Unity3D.

In this tool you can also filter your HDR panorama map to make diffuse convolution or blur reflection, converting, and export panorama file into various format HDR skymap or cubemaps.
From version 3.0 with new feature “Fast Sample” to let you generate blur reflection in high sample just a second. And support to generate pre-baked Specular Chain in Mipmap base on your glossiness setting.

For this version, the major change is the new feature: Support Radiance HDR(.hdr) file import as a HDR source.
That mean you can import any HDR Panrorama image in SkyCube and convert it to your scene as a HDR cubemap or skymap.

V3.0 RELEASE NOTE
• New Feature: Unity5 Compatible
• New Feature: Fast Sample to generate blur reflection in high sample just a second.
• New Feature: Baking Specular Glossiness Chain in Mipmap.
• Bug Fixed: Fixed HDR maximum range update issue in both mode.
