Help Fluid rendering on small scale

[felste]

I need to use Obi fluids on a small scale. I've been scaling the solver to 0.2 uniformly with the emitter being a child. The fluid works fine and the particles are rendered correctly. However I have problems to render the fluid as a fluid. Already tried turning down the thickness cutoff in the fluid renderers settings. Still the fluid is almost transparent. Having the solver scaled to 1.0 the fluid looks fine.
Thanks in advance!

Still the fluid is almost transparent.

That's probably due to absorption:

Absorption simulates how light decays as it travels trough fluid. If your fluid is very thin, it will look almost transparent since light travels a very small distance inside the fluid. This is intentional, it is the reason why many fluids (for instance orange juice) look almost transparent when only a thin layer is dropped on a surface, but when you have a glass full of it it looks almost opaque.

Cranking up the absorption parameter in the renderer will bring color back to the fluid.
