A little later than originally planned, but we thank you for your patience! One of the most exciting things we wanted to deliver with our Premium tier was a renewed commitment to Tech Focus - Alex's 'explainer' series on the technologies and techniques used in modern rendering. And they don't get too much bigger or more complex than global illumination!

The video is available both for streaming and for download and we'd love to hear your thoughts on it! Similar to new DF Retro episodes, the content will remain exclusive to the DF Supporter Program until the next offering is complete. Thanks for your support in making this possible!
