Zero Gravity was a project that I started to learn more about PBR and Unity 5. It ended up into this small environment that could be used for everything. It´s also very optimized so even mobileVR could work but will need more testing.
This work has been featured in 3dtotal.com gallery, CG Choice Gallery, InCG Magazine, 3D Artist Magazine and in many other cg-related site. I also wrote couple of articles about this into various magazines. Scene was also playable in the GDC 2014 expo at the Marmoset booth. Making of can be found here http://kimmokaunela.esy.es/lfi02.html. You can get this project from the AssetStore: https://www.assetstore.unity3d.com/en/#!/content/25579
