We all know that HDR Images produce superior reflections when used as environment maps.
However a lot of HDRIs are supplied in formats that are not specifically shaped to be optimal for spherical mapping.
They often are created using the popular probe method, or alternatively, you might have some that have been generated using the cross method.
You can see an example of such formats below.
Well luckily for us, Cinema4D comes with some tools to take these formats and convert them into the more usable spherical map.
If you go to the Render Menu and scroll down, you’ll see two entries.
Convert HDR Cross…
Convert HDR Probe…
Well it is really as simple as selecting the command, then choosing the appropriate HDRI.
Cinema will then perform the conversion and resave the HDRI in the same directory. The Filename will have the addition of _con to show you that this is the converted file.
