I used both Tim's model and a custom design for my Render Weekly shots this week. It gave me a chance to try out some more volumetric lighting with 'god rays' and to have a bash at creating falling rain in Keyshot. I will finesse some of the method for the rain and share it in a YouTube video soon :)
I also used Instagram@thedesignformula 's Terrazzo material from the cloud in my custom design. It's such an awesome material and really easy to customise into a different colour scheme. My students are going to happy now there's a readily available terrazzo to use.
