I've spent the last few years with Corona Renderer. Now that Redshift is the default renderer in Cinema I thought it's time I explored its potential. This class uses the old Redshift 'stuff' and I did get stuck a couple of times making, for example making the metallic material using C4D2023 and some render settings. Considering I've never opened Redshift before today I'm happy with what I've learned. 

For the record: Intel 2019 iMac. i9. Redshift Rendered in 2m 25s

and Corona rendered it in 0m 54s
