SkyCube RT v1.0 : Real-time IBL HDR Cubemap Rendering Tools & Shader Libs

June 4, 2015

RT46

SkyCube RT is a tool with shader library for in-game 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.

The tool orients Unity4.5.x and compatible Unity5.x. And it will render cubemap with specular chain at the same time (in real-time), it means you can access different roughness reflections in one cubemap and also can use them in one object, for example, like multi-layer reflection material.

Besides standalone version it had already been included in Skycube since version 3.5, you can find it in Asset Store: Skycube

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.
