Hi,
I noticed some nasty flickering when the sun size is set to less than 1. It goes worse at it approaches 0. I attached an Houdini scene even though I guess that it might be more related to Octane itself.
Hope this could be fixed rather quickly as we rely on sharp shadows and a nice physical sky...
*edit* : forgot to tell that it happens when time is animated (it's a timelapse)
Thanks!
Ben
