I just started out with Unigine yesterday so I might be missing something, but I seem to be getting 100% glossy screenspace reflections on Linux. I set up all materials to write to the auxiliary buffer and added the vanilla screenspace reflections post effect shader to the Render stage. I'm using an AMD FX-8320 and an Nvidia Geforce GTX 780 with Unigine 2.0.1, kernel 3.19.0, glibc 2.21, proprietary driver 355.11 on an Ubuntu-based distribution. Can anyone reproduce? I'm going to pop on over to Windows and see if the same thing happens there.
