Hi Folks,
I wonder if anyone can help out with explaining some Poser wierdness, and hopefully how to avoid it.
I have noticed that when I use Ambient Occlusion (AO) to get better shadows at skin-to-skin contacts, I sometimes get white lines appearing where the shadow should be darkest (like a dynamic range overload causing an inversion... or something like that).
In panel A of the picture is the kind of AO shadow I expect, but even here if you look closely (see panel B for magnification) you can see the beginings of the effect.
Panel C (a picture of gymnastic contortions :) ) shows that in some shadows the effect is there (red) and in others (green) it is not.
In some images this artifact is very strong, with a really white line running down the middle of a shadow.
I am using AO on the shaders (AO on lights switched off), using Occlusion Master (by face_off) and Unimesh Realism Kit (also by face_off).
Obviously this artifact is due to the lighting but I'm not sure what aspect of the lighting is causing it or how I can avoid it.
I use an IBL light and spotlights (usually a light set by R3DF).
If anyone can ... er... shed more light on this problem I would be grateful.
Thanks,
Isaac
