hi xpdev

this is just one of those battles I like to win (from Poser, not from you). nice scene, by the way. yeah, I'm sure it's not in the materials as such, but materials do get in the way of interpreting the results, so "we can see clearly now".

It's something in the scene, in the lighting or in the interaction between them. Sometimes an object, in sight of at our back, is standing in the way somehow and generates a somewhat unexpected shadowing. That's wy I also suggested to make everything invisible, except for just 1 ground 1 roof 3 porch walls and 1 couch in the front. That's what I had in my test scene, and the extra shadow line did not show up.

When all material issues eliminated, and all object interferences are eliminated, and the issue is still there, then we're sure that it's the lighting interacting with the extremely simple porch setup. Than plan A. If the issue seems to be disappeared, then groups of objects can be made visible again until the issue re-appears, and in that way you can find the culprit.

plan A: try to find out to what extend the issue is a result of your render settings. First, increase the bounces (till max). Than increase IDL quality (till 80) then caching (till 80). All in steps, or just the max setting first to see if the issue is still there.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
