Alpha "density" / Particles and TFD

[Jahe]

Hi there!

Is there any trick to adjust the density of rendered Alpha channels in Octane?

In my situation I have particles (rendered via Octane Object Tag) and a TurbulenceFD Simulation (also rendered via Octane Object Tag), both very visible in front of black, but definitely out of focus.
Very visible (bokeh-like) element but the alpha channel in those areas is very very faint, almost not detectable.
I would expect the alpha to be at least as bright as the luminance of those elements but it´s not.

Cranking up the Alpha with curves wouldn´t help as is destroys other alpha areas,

Any idea on how to fix that?

Thanks in advance!
