Well.."Sr3...Sr4". Lately, been playing around with the lighting(s) for my Animation Scene. One light, render stops half way, add a few more, render starts to happen but slowly. Go into the Material Room, select "Atmosphere", click on "Volume on", And the render just stops, half way or even or even yet stops before Rendering. I believe as well, their is a lighting issue. Press on Cancel, Poser hangs with a message..."Canceling". I always have to use "Windows Task Manager" to close poser when that happens. Image Example: Rendering hasn't started yet, and I get this hang.
