Re: PhotonGI cache

Can there be some cache filtering for reflections?
Wanted to test older scenes wigh gi cache but there is no way I'm going through all materials and deciding if they need to have photongi disabled.
And probably every complex scene will have a ton of glossy materials that won't work with gi caching because of the reflections.
I don't know what vray's retracing does though In a scene like the office I made, pretty much 75-80% of what's on screen is reflective enough that I have to disable photonGI for materials, this leaves at best only walls to be able to use the photonGI and while it does gives some benefit still.. It's just not worth all the work on deciding and testing wether or not I can or can not use photon gi per material.
This is not good as I'd rather take slower solution than have one more thing to worry about that could go wrong. Especially for complex interiors with a ton of stuff, and not mentioning having an database of ready to render assets, that need revisiting in case they need to be used with photonGI.
And one suggestion for blender addon. The lower limit for photon cache settings seems to be 1000. Wouldn't it make sense to have a [number field] and letter "K" behind it? Suggesting this is numer x 1000 so that users don't input numbers like one hundred million ? Or do you think it would look messy in the UI? Maybe just a tooltip that the numbers are in thousands? I just feel silly counting the number of zeroes so that I don't accidentaly use billion of photons
