I have got into an odd problem. I have been rendering a character (originally from Blender Swap). It is fully textured (skin and clothes). I have been trying variations with the node tree for the skin material (using ColorRamp & RGB curves.)
The World consists of he renders of a large curled-up plane, strength=.6 and AO fac=.6.w
The renders were going well when one of them at the last second suddenly brightens up and then goes out of focus. So I am lumped with this somewhat blurry image whereas during the render process, the image was crystal clear.
What might be the problem?
Help will be gratefully received.
