I'm shopping around for a solution. Right now we are using, in UE4.22 the Scene capture system (5 capture cameras) blending into one 180 deg dome.
we are unsatisfied with this solution since particles go not work seamlessly from one cap camera to the next.
would Octane allow us to create a one camera 180 (semi-sphere) render with realistic lens distortion, and not linear pinched in the center.
if yes, would particles work with this? We are working on large outdoor landscape environments, clouds, fog, shadows, foliage...
