The feature is going well, slightly bumpy as I have to handle thousands of other things as the co-producer. Being an art-house animation working with co-investors is sometimes good other times challenging. Planned to finish it by 2020 end, but it might take longer.
For the short,
It was a single machine i7 (3rd gen if I remember correctly) with 1 GTX Titan 6 GB that handled all rendering.
Maya 2014, Redshift for rendering. When I shifted from Mental Ray to Redshift it was still in Beta but really did the job well. Now it is much more robust and rendering for the feature is much smoother.
Photoshop and AE for compositing and Premiere for edit. Mixamo for crowd animation. Google Docs and Dropbox for housekeeping.
As for the team, 3 friends (Yiming Lim, Nicolas Agatha, Milan Padhiyar) from different corners of the world, helped me out voluntarily to do the challenging animation shots, as I am not much of an animator. There were around 14 such shots. Everything else is me.
