This year our studio inherited the amazing Arnold renderer and a bunch of licences for us to use in C4D and Maya. Originally I was planning to learn Octane after so many impressive pieces from artists such as Beeple and the clever folk at Elastic. Due to still being locked into my Apple bubble and not having Nvidia cards, this wasn't really possible so Arnold it was.
Initially it was quite daunting.
Firstly the viewport doesn't show materials and mostly textures need to be build from scratch using the xpresso editor. The amazing render quality more that makes up for those shortfalls and I quickly started doing tutorials to get my head around the new workflow.
Some work I've made so far:
I found some great models from threedscans.com
