I saw this linked which was an interesting look at some of the special effects used on the new series of man in the high castle an amazon show
I've not seen this show as yet (it's on the long list of things I mean to check out but never seem to have the time for) but what caught my attention is that this VFX company are using the opensource cgi program Blender with the Cycles rendering engine as their main modelling and rendering package (they things like nuke and after effects for compositing houdini for particles and substance painter for material generation).
Now blender pops up all over the shop in all sorts of contexts it's amazingly powerful does a huge number of things well that a lot of other expensive programs can't and of course it's free but often it's small projects or throwaway tech demos (for instance the most recent promos for AMD's Ryzen used blender extensively in benchmarks and the indie film and essentially gopro comercial Hardcore Henry used it for it's special effects) but this is probably the most high profile use of Blender I've seen to date.
It's interesting to see something like Blender which is often dismissed as amateurish used in a high quality commercial VFX production pipeline.
They also did a AMA where they talked about the process and their reasons for choosing the software they did in some detail https://www.reddit.com/r/IAmA/comments/5rvwo2/we_produced_the_visual_eff...
