Just a question, are Realtime Reflection Probes supported or should be working in our PG world? Made numerous attempts without success.

I don't know.
 

They can be a killer on performance though, unless you're not using TOD so can do them really infrequently, as you might do to sample the in-game lighting rather than non-realtime probes sampling the Editor lighting.

If doing them too slow with TOD, you can notice the reflections change in steps.

Yes, sorry. Realtime reflection probes are often used for capturing the changing scene during the ever changing day cycle so the reflections for instance on a lake don't show a sunny sky when it's now progressed to dawn.

If you're not planning to have it recompute the cubemap frequently during PG's TOD mode, the default 'on awake' refresh mode would be ideal and performant. However it might occur when the scene is loaded from the course before PG adds in the lighting. Not sure, never tried it and just hypothesising as you're finding it's not working.

Made a last test and it didn't work. So will stick with baked/custom probes. And as you said, it probably wouldn't be worth it anyway for performance reasons.
