Hi...
Any idea what might be causing these 'black pixel' type squares appearing?
I've taken the following steps attempting fix this issue...
● Turning the lights and other light related settings 'on' and 'off' one at a time (trying to isolate the problem).
● Re-open the project after shutting down iClone 7.2
● Re-boot the PC
None of the above solved the issue.
The only thing that (predictably) toggles this issue on and off - is checking / un checking the Depth of Field's 'Activate' box.
Also:
● Larger black squares (but fewer of them), appear on iClone's 'preview' window. (see pic 1)
● The rendered out image has smaller (and more numerous) squares.(see pic 2)
● When resizing the preview window the position of the squares changes randomly.

Close examination of pic 2 shows that the squares only appear INSIDE the DOF blur range; ie: in front of and behind the 'IN FOCUS' plane.
It seems that the blur calculations are messing up somehow.

Strange thing is that I've played with the DOF before going back a couple of weeks - and no trouble as of then. (Don't have those files tho).

Any clues?

EDIT: Also, the spots on the rendered out image (pic2) - actually more closely resemble circles - which is interesting because I had the 'Bokeh Type' set to Circle.
When I select a different Bokeh shape (say 'star'), - the black shapes in the preview window will resemble stars. - Definately changes with Bokeh shape....
