PhotonGI strength
Posted: Tue Aug 13, 2019 8:30 am
While doing some testing I found out photongi to be a little too strong with lighting.
here's sun and sky in luxcore without photongi: for comparison here's cycles: now of course it's different and very hard to match them cause sun and sky in cycles works terribly, but overall lighting distribution seems more or less the same, nothing weird is happening...
now here's photongi with default values in blender:
you can see how is the scene flooded with light with objects on the ceiling almost looking like some fake AO is going on.
And here's photongi with photon depth set to 3 (default in blender is 8): now the lighting is much closer to the non-pgi render while performance boost is still present
So my question is, what is happening with more photongi bounces/depth that gives this strong lighting?
