Review on Arnold by Luis Green

The ability to render images in real time with minimal resources makes it ideal for simulation workflows. I like that you can use it as an interactive rendering tool or create static renders without having to worry about performance issues. It's not perfect - there are some bugs here and there but they're being worked out quickly by the development team! There isn't much else to dislike so far. If you want something simple yet powerful then this should be your choice. We've been able to do simulations of large structures using Arnold at very low cost compared to other software packages.
