I removed the CC-BY-NC Skybox so that there is no conflict anymore for commercial use.
By resaving the asset i saw that i used Apartemento instead of Apartamento, so i fixed that.
For the people who have already created scenes with this asset, i'm not sure if the scene loads correctly
with the new Var file of the asset or if the asset has to be replaced and the scene resaved.
Name and and Folder in the Var file of the assetbundle files are the same, just the Var and
Scene Name have been changed.
