Hello
I am trying some fluid dynamics inside blender...
But when I compare the rendering from a specific time with the animation the look is totally different:
Still image from fluid simulation:
And this is a screen shot from the animation:
Both images are taken at frame 60.
Rendering the animation in Cycles looks correct like the still image.
Constant crashing during rendering is another thing (o;
[Solved] Animation and still image rendering differ
Interesting to note....
when Cycles and Octane are both set to 200 samples limit, Cycles with CUDA using a GTX1060 6GB on Linux is way faster than Octane with a GTX1080 TI running on macOS.

Wrong animation rendering with Octane for Blender:

It looks to me like OctaneRender always uses the maximum mesh extent of the fluid
and doesn't take into account newer smaller mesh dimensions.

Okay...got it....seems the Flip Fluids demo plugin doesn't auto-detect Octane as the commercial version does...
So you need to set the Mesh to "global" for the fluid...
But black frames in animation rendering still persist...

I'll check FLIP Fluids in Octane 4 again.
Never had issues with the render.
