New to helloluxx is the CG HDRI : Sky Collection from Shawn Astrom over at SA Studios.
The CG HDRI : Sky Collection pack from SA is an amazing set of HDRI skies that were rendered in a 3D program at the resolution of 16000 x 8000. Not only are they extremely high quality, they also include an alpha channel for the cloud layers so you can cast fake ground shadows from the HDRI files, with traditional HDRI spherical maps, this was nearly impossible to do.
There are similar products available however the major difference between those and the CG HDRI : Sky Collection is that the others are traditionally created using photography. Another difference is that the CG HDRI : Sky Collection have a CG look to them which may be desirable depending on how they are used.
Below is a manual that Shawn created on how to properly use the images inside of C4D and with VRAYforC4D. It should also give you an idea of just how beautiful these assets are:
