Precached map has low continuity ratio...

Precached map has low continuity ratio

What does it mean?
How does it affect rendering (because low ratio is rendering slower? noisier? ...?)
How to elliminate this message?
Do I have to care about it?

This is information about fill up scene by photons. G. add this to see is there problem with photons in corners and general.
The best solution is use 40 bounce lights - like G. suggest to achieve minimum GI solution as real behavior of real GI.
Also I suggest use minimum 100.000 photons multiply by 20.

Precached map has low continuity ratio has not so much influence for quality becasue we have also other tools for fix problem in corners:

This tell us about one bounce Path Tracing Photon and distance from corner. This helps also reduce problems in corner and actually is necessary.
1/50% is accurate value. Is no sense add more Path Tracing photons - enough just one or increase distance from corner.

Also QMC sampling do his own job by correcting corners.

These all tools allow K3 render GI quality which is available in Path Tracing by Photon Mapping without speed limits or bounce lights limits.

Suggested settings for Photon Map solution:
