Yes, my second test also seems to be rendering. I think my problem was exceeding the number of instances, I literally had legions of bottles. I brought the numbers down, and so far it seems to have worked.  I am crossing my fingers.

 I am now starting to discover the mysteries of the replicator. Is their a command to do this?

My MacPro has 6 GB of RAM. It might be able to handle it.

 I tested it with one single instance of the bottle. It renders fine. The problem seems to be caustics + replicator. I will try to experiment with the numbers on the replicator and see if I am simply getting a bit over my head as to how much Carrara can handle.

 Thanks Mark,

It should be simple to figure out. It's a model of a bottle using the "replicator" feature. The funny thing is that it renders half way, so I am puzzled. But the caustics would be rendered on to the floor of my seen, I think that is where it crashes. I will attempt to render the object with out replication, and trouble shoot it from their.

Thanks again Mark.

 anxcon: No he does mean 8 cores on one computer. I have one too.

Toxe: Your render is so short that you gain little from all 8 cores. As I understand it, it takes also processing power and time to distribute the task for multithreading applications. So in your case this is taking longer then the processing it self.

I had a project that took 47 hours to render on my dual 2.3 G5. It rendered in a little bit under 8 Hours on my MacPro. I love my Mac. :)

 I wish I had time to watch them. With my schedule, I think I would be better off buying the set then dealing with the 30 subscription. But I am very tempted to do it.

 Well I got the system, and it's everything I hoped for. So you can say that Pinklet lived happily ever after...

 Yes, I got the domain naming and UV mapping down. What I don't get is that the displacement section of shader UI does not allow to name a specific domain. How do you access the specific domain that you want the displacement to take place on?

 How is this implemented with 6.1?
When I try to setup a Displacement, it's ether the whole object, or the whole object.

 Mark:
Very nice portfolio. Very versatile indeed.

 I think more the processing power Apple had a pretty crappy bloated system. OS 9 crashed at least twice daily. Their towards the end it became increasingly unstable. Then came the first version of OS X, that really was not all that optimized in it's first incarnation. Once Panther OS X 10.3 came out things got a lot better and increasingly stable. The switch to Intel was a brilliant move that Apple had planned since they ported NeXT to the Power PC, but still developed  a secret version for the Intel architecture, as a brilliant plan "B" strategy, that apparently  is reaping huge benefits. The G5 was not a bad processor, but it was power hungry and ran hot .

I had the last of the Power G4 dual mirror door boxes, the wind-tunnel model. It was like working with a semi quiet blow dryer. I did get used to the noise, did not realize how annoying it was until I got my G5 that would on occasion  rev up those fans. But I though that was kind of cool sounding (on the G5, not the G4 that was incessant noise).

Now tomorrow I get the Mac Pro, from what I hear it is a very quiet setup so I am not to sure if I will miss the fans on the G5 :)

 Thanks Patrick_210, I am sure I will be needing this tip also.

Thanks for your input. I really have almost 0 need for Windows. I have been using Mac OS since 1988. All my software is Mac compatible and even thou I have to acknowledge that as far as 3D goes, Windows has more choices, I have always preferred the Mac. To me this boot camp thing is really a safety blanket to diminish the fears of switchers. OS X is by far a better OS as far as multitasking and general purpose computing. Windows is still very good and doing one thing fast at a time, like gaming. Since I am not much of a gamer, I rally don't have any need for Windows and all the headaches it entitles. One possibility that  dose come to mind would be to be able to test my web site work on Windows, but I have a Windows box for that already.

This is purely anecdotal, but all the people that I have helped switch, installed Windows on their initial setup. Only to take it out a few months later realizing they did not have a need for it like they though they would. Companies like Adobe offer side-grade deals so you can switch your license from PC to Mac when upgrading. Macs don't have all the plethora of choices that Windows do, but almost in every case, you are able to find a Mac counter part for any Windows application that you may need. Since the Mac market for software is not that big, developers can not get away with crappy software, so usually all the Mac software is of top notch quality also.

The other curious point is that they have all become staunch Mac supporters (switchers). Almost like dealing with ex-smokers, who not only give up smoking, but end up hating it more then those that never smoked.

 The setup is pretty easy. Something that I just found out is that if you place a patch on Carrara you also need to patch the node. It will not work if they are not exactly the same version. Also, start up the node before you start up Carrara, for it to see the node.

 David, let me stress once again how grateful I am with your offer. I took the plunge and ordered a MacPro as soon as I got home this afternoon. I had a buyer lined up for my G5. And the client that I am doing all this work for is worth the investment.

I purchased it from Amazon, got free 2 day shipping, $150 dollar mail in rebate, 12 months with out interest and I paid no taxes. So the savings are close to $400 dollars all together.

This computer will have paid for it self in two months so it was a no brainer.

Thanks once again David,

Cristian
