I'm making a video that shows all the phases of a construction site, and I have to try to optimize the performances in the best way.

I noticed that pass a lot of preparation time for each frame, there is some way to optimize?
Every scene are quite simple with few polygons and materials.
I'm working on:
MAC 10.13.6 + GTX 1080Ti - Driver NVIDIA 387.10.10.10.40.128
SLAVE Win 10 + 3x GTX 1080Ti + 2x GTX 980Ti - Driver NVIDIA 419.17
C4D R20.059 + Octane render 4.03
Thank You
Stefano
