Black Magic just bought Eyeon software, maker of Fusion, the node-based visual effects software used on The Amazing Spiderman 2, Orphan Black, Battlestar Galactica, etc. So Black Magic is offering Fusion 7 for Windows absolutely free! Full-featured! https://www.blackmagicdesign.com/products/fusion
I've used it before, takes a little getting used to node based compositing if you have never done it but well worth the time investment
Looks interesting. Anyone know if the particle system is as robust as maya effects particles
