I have to render a quite big water simulation done in Liquigen.
The built-in Liquigen render engine would be good enough for what I need but I need to render with a spherical camera, so I would render it in C4D+octane.
Problem is... switching to octane takes more than... 2min per frame ! (resolution is 6800x3540)
Liquigen renders in less than 2seconds per frame !
I am wondering why there is such gap between Liquigen & Octane. I just need a simple water shader with a reflection/refraction, no GI or HDRI required.
Does anyone have tips on how to simplify the rendering to the lowest possible rendertimes ?
Or how to render in another app or render engine entirely, who would use GPU rendering & spherical cameras, matching the look below.
Also another problem is : the first frame renders normally, then the rendering time increases significantly over the following frames...
Seriously... WTF ?!

I won't consider online rendering because the sim file would take a whole day to upload with my bandwidth...
Thanks in advance !
