I tested that in the simple scene posted above and found that light tracing (and caustic cache) don't work with with indirect light.
Now I see you have already written.
You could try Glossy (or Disney) walls and door frame, and increased Glossiness Threshold of Light Tracing.

Then I realized that when rendering with indirect PGI indirect caustic paths don't connect to lights but end with a cache lookup.

Why don't you try it with Light Tracing?

If you post a test scene, I can tell you what is going on.
Here you go and Thanks!

(I know, that there is no point in mixing Glossy with Matte. It came up in this topic: viewtopic.php?f=4&t=1372)

Re: Path Space Regularization (aka the solution to SDS paths)

My experience is, blurring does not decreases (at least not in a humans lifetime).
So you must find the perfect value, if you set too low there will be no SDS samples, if you set too high, it will be blurred forever.

even so.. Sun so strong it forms nice and crisp sds caustics but yet no bounce light on walls from it??
I see the light bounces on the walls...

Re: PhotonGI cache

Is it a known issue or maybe intentional that PGI doesn't work on Mix Material, even if the mixed materials would work in themselves?

Re: PhotonGI cache + Oidn params

- I used PGI Debug: Show Indirect for er, uh... debugging :) I did but I really don't know how those spot means. Are they correct? Those spots look good enough to me. Spot size is defined by Lookup Radius, and more Photon Count means smoother look, or less difference between adjacent spots. But for...

Re: Path Space Regularization (aka the solution to SDS paths)

- Glass volume absorption gets very saturated during Light Tracing with PSR Do you have an example ? - It seems to me, that Light Tracing and Path Tracing brightness add up in some cases, so (without clamping) Hybrid becomes brighter than BiDir or simple Path tracing. Do you have an example ? I thi...
