Geez! Seems to be my time for running into bugs.

Here is an interesting one. I have a scene that renders fine for as long as I want. However, if I remove all light sources and enable Alpha Channel in PMC, to get a black object mask on transparent background, it fails after a few minutes. Can even happen when resolution is set low, but not always. If I use a high resolution, the failure is pretty much guaranteed (at least with this file).

Might have found the solution. Worked once anyway...DON'T disconnect the light sources. Keep them connected and just drop their powers to zero.

Thanks for the bug report. We will have a look at it. You don't have by any chance an example scene? Thanks.

I'm right in the middle of a render that I am going to let continue while I get some sleep. I'll send you out the file tomorrow. (It's 3:30am here)

Chris,

Do you have a temporary upload address...The orbx will be way too big for the forum.

Thanks!
