Point density halo particle system not rendering 'head on' Rendered:


Refuses to render (Seemingly) outside of emitter:


Even when on a separate layer:


There is a rendering 'domain' that is sufficiently sized (Since it renders in the first instance) and it's not range clipping related so I'm sort of stumped.
The rendering issues seemed to be tied to how massive the scale of the project was (Needlessly, too).
Scaling down to 1:10 (The object is now 100m long, not 1km) seems to have fixed the issues with rendering particles at all angles.
