MODO | Octane
Volume lights in Octane are possible - albeit a pita to set up. Looking forward to ‘Spectron’ (really OTOY, Spectron? Did Brad Peebler come up with that? Has a 'skelegons’ kind of feel to it…) where we will have an easier time setting this stuff up.
BTW - you can texture emitters to break up the volume…change light color (or emission color) and/or scattering color to tint the light rays.
