Just come across this new real-time raytracer called
FluidRay. If you scroll down to the video, you'll see that the interface is exactly copied from Octane. All the GUI elements are there, which is kinda expected, but they are also designed very similarly: the outliner is almost the same, the "node inspector" is exactly the same (crowded as in Octane). They even copied the top-down graph editor, which, frankly, isn't a that great design (most other engines use a more ergonomic left-to-right approach).
I guess someone is trying to ride a bit on the Octane wave

(or the same GUI library was used to code both

)
Anyway, it looks like just another generic "real-time" "physical" renderer, the market is flooding with. Nothing special. (CPU & Win only)
