Hi!

I am just downloading my first rendering. All I can say is : AWESUM!!!

Anyway, I realize that memory (of course) is an issue. Yet I do have an surplus with scenes that contain particles (fur). CPU-time is not  so much an issue here but MEMORY is. Particlerendering, no matter how restrictive am trying to be, -easily- cracks the 1.5GB-border... and above.

ATM I do not think it's a good idea to upload such scenes  because I suspect the nodes going havoc about it (and swapping their HDs to death). Forcing a node to swap like hell also wastes CPU time and consumes time that could be used for other users/participants.

I wonder if there are any people here who have some experience that: Renderfarming.fi and particles. I would be very glad if your would share your experiences with me =)

3GB or less and you are fine.

3GB or less and you are fine. The less it uses the better though. I'd write a long reply, but I'm tired after the BOINC workshop day here in Hannover.

Well sometimes a short reply

Well sometimes a short reply is better then a long one... especially with good news. So I won't worry too much aboutthat. Thanks!

I know my latest scene is full of hair particles.  What can I do to bring them down below 3GB?

Captain Obvious sez: Keep the

Captain Obvious sez:

Keep the parcticle count as low as possible-

If that's not an option consider going for several layers (per object) with offline compositing afterwards ;P

I *just* started working with hair particles -- don't feed me to the wolves just yet!

I could cut out one particle system entirely, but the other I really can't do without.  Unless I can compensate by turning the number of children up.  It's a grassy field, so both particle systems are associated with the same object.

Not sure if this will help,

Not sure if this will help, but there was a highly exceptional Cycles scene where the memory usage was kept low for a scene with high model count by using instances. Something like that might work.

Thanks for the link! :)

Thanks for the link! :)

I haven't played around much with Cycles (yet).  I'm on a deadline so I won't have time to tweak this scene in Cycles until summer.  It's worth a try!  :)
