The Material System in Arion is getting incredible improvements for version 3.
An example: The new 2-sided material allows the use of two completely different materials for the front side and the back side of a thin object (without a volume). This can be used to simulate sheets of paper, tree leaves or, like shown on this example, a set of playing cards. We have updated the Arion v3.0.0 page with some high resolution examples.
Here are a couple more examples also using other cool new features that will be announced soon:
Thank you for watching!
