All made in a Blender and Octane Render. The speed of the rendering engine knocks me to my knees. Active renderings of the 1h 30 min at 120 frames about 39 - 45 seconds per frame. Number of samples 500 and environment octane type daylight system. Standard light settings, I used also a light depth of field. Motion blur shutter value 0.36 and motions samples values 14. Rendering did not go well, because not to bake frames of simulation, forgot about it.
