Hey all,
Thanks for all the replies. I spent a few hours messing around
with the network rendering the other night, and I found the problem.
The network rendering actually does work (as I had it set up), UNLESS
I have either "sky" or "realistic sky" in the scene...I can get any
scene to render if it doesn't use either of those in it, and inversely
if I add either of those to the scene the network rendering won't
work. Odd? Yes.
Now, before I go and submit a bug report to Eovia it would be
really great if some of you could try this, see if you can use network
rendering on a scene with a sky simulator. Then post your results here
(with stats on your Carrara 4 version [patch or not], computer specs
etc.) Then I'll have a solid base of data for the bug report, then
hopefully Eovia will be able to get it fixed ASAP. Thanks everyone.
