Are real-time reflection probes working with specular convolution on mobile devices?

As I haven't heard any feedback in "Answers" section since I asked about this nearly a month ago, I figured I should try the forums.

Suspecting specular convolution was simply missing from the real-time reflection probe's render target on Android, I modified a custom shader to simply output all of the cubemap's miplevels. As expected, only the full resolution reflection was present. None of the mipmaps were ever updated with specular convolution (they remain black). This was true regardless of which real-time reflection mode I set the probe to use, enabling/disabling time-slicing made no difference.

My initial tests using custom shaders I authored for our project appeared to prove that real-time reflection probes do indeed work on Android. Updating reflections every frame was, as expected, fairly slow even with timeslicing enabled, but it did appear work...because the shaders I had used in the test simply displayed the reflection probe's cubemap at full resolution (it just so happened that all of the specular materials in my scene at that time had glossiness set to 1.0). To improve performance on hardware, I elected to trigger reflection probe updates via script and reduce the resolution of the cubemaps...which is when I decided against ever having perfectly smooth materials. And that's when I started noticing that the reflections would drop glancing cube-facings or fade as the camera pulled back from the surface.

Custom reflections work fine on Android and are my present workaround (the probes are still set as real-time for PC, but the script I use to trigger probe updates switches the probe type to custom on mobile devices). I was hoping to take advantage of script-triggered real-time reflections so I wouldn't have to store files for every environment / lighting scheme we plan to load at run-time.

Is this a known bug or simply a limitation of real-time reflection probe implementation on mobile devices? I haven't even checked to see if this is the case on iOS.

 

Anyone?

 

I'm having the same issues.

Realtime reflection probes on ios set to update via scripting are black.

The work around is to set a custom reflection probe.
create a legacy cubemap texture, Set mip maps and face size and readable in inspector.
Assign this texture to the reflection probe.


instantiate a camera and rendertocubemap(into the created cubemap texture).

 

Awesome. That works on target hardware! My script now generates a cubemap render texture, briefly associates it with the main camera where I call RenderToCubemap on the first frame, then assigns the texture to the probe.

Ironically, reflection probe custom texture baking, real time reflection probes, and RenderToCubemap appear broken on PC (when running in OpenGL mode) in 5.1.1.p2...
