Hallo,
thanks to this awesome GPU render. Here is my first small project I work on, it is still in testing stage. I work on windows application, also HTML5 is possible now such as android. (yes, with a lot limitation) Now I am trying to export 360 VR also. These examples are from windows version:

Anyway, is in plan to add own light sources? I know that it is possible to simulate all by emissive material, but in backward doing solution for GI this method produce a lot of noise. SO would be cool to have own GPU forward computing light sources with subdivs parameter or just something better than UE lights. I just hate the crazy quality and bottle neck CPU power of UE lights.
Also is different of memory consummation between GPU or CPU GI? I have actually the biggest problem with GBram, not with Vram. I have 64Gbram and 11 VGBram. This scene took more then 64 gigs and just 8 VGBram. SO I would do better resolution for textures, but I am actually limited by GBram of my computer. I used the CMD line to save some ram, but that is just not a solution.
Also a support of translucency (just for courtains) would be great
