Thank you guys ! :)
Yes render with my i7-6800K takes time, but it’s not a big deal. It allows me to take my time.
Usually, I work 1 week peer sequence, then there are between 2 to 3 weeks of renderings. I don't render during night, nor during my working hours.
Maybe in the year i would change to a threadripper ryzen and 64go.
Some of my acquaintances tell me that Corona is not made for film, just a freelance engine, and others bullshit like that.
Ok so here I told to myself, I'm going to make a 4k movie :p
To return to the split, I put 2 images showing how I do it. Nothing sensational.
I just created a behance page if you want:
