On a side note, it was not 10000 individual objects, what it was was 1 RB object, with a # of copies set to 10000 and for the x position ($OBJ*1.1) this created the 10000 objects I wanted, and when I tried to simulate (having created a ball that hits the first domino like object beforehand) Houdini had a fatal error

What I was trying to replicate was the domino video located somewhere on this site…demoing the ODE DOP option…wether or not this was done on a Windows based or Unix version of Houdini or not is beyond me (I am assuming of course the sim may have worked on a Win based version of Houdini), but as stated before, ODE doesn't work with an object count of 10000+. It was just to show a buddy of mine the power of ODE, however it just merely illustrated it's unfortunate limitations…sim still worked with RBD, but OMG, it causes SO MANY penetration errors, I nearly wanted to puke…

On a side note, I would like to thank SideFX for incorporating this wonderful physics solver into their program…
Pros:
Cuts render times into mere slivers of what it would take with RBD
Works well and produces far superior results with less penetration errors
many more…
Cons:
Does not seem to work with 20000+ objects, Always causing houdini to crash
As stated above, the ODE physics option is great, however it does not seem willing to work with an object count over 10-20000. Note that I am using the most update version of Houdini (daily build as of February 14-12th-ish) and am using the following computer:
MacBook Pro Late 2009
NVIDIA 9400M/9600MGT (9600MGT primarily)
3.06Ghz Core 2 Duo Processor (Intel)
500GB 7200 RPM HDD
4GB DDR3 RAM
OSX 10.6.2
If anyone has any solutions to this problem, or are aware of any makeshift patches that can be made at the present time, please let me know.

How can you possibly state that it is fixed, when the only time you can get the DAILY VERSION RELEASES is when you are logged in as a fourm member? It clearly hasn't been changed so non fourm writers can access the latest build and SEE the fixes!
Actually if you go to this page:
http://www.sidefx.com/index.php?option=com_download&task=apprentice&Itemid=277 [sidefx.com]
you have access to the latest production build which was updated yesterday. (build 10.0.465). Of course it looks like you are registered as a forum member so you must have already tried one of these builds. Are your SL problems taken care of now or are you still having issues?

PS - Please clean up the foul language in your posts or they will be deleted.
The graphics card issue is in order however…
(I hope you will understand this)
When installing the latest build ON TOP of 10.0.430 with MANUALLY adjusted permissions = fantastic, 100% complete installation; no major bugs.
However:
When installing latest build AS A CLEAN INSTALL (no other Houdini versions prior installed, fresh copy of SL) Permissions problem still exists and needs to be repaired manually.

Well excuse me for expressing frustration without dropping the cuss bombs!
Now then, are you saying that SL is a COMPLETELY new platform compared to Leopard? The only thing that has changed is driver support, stability and overall OS hardware management. As Emeek stated above, all other pre SL 3D apps are golden on SL.
Communication problem? I read the information on that site, and all SideFX says is not to upgrade. Well that's great, but what if it is required due to better physics engines and ease of use? Houdini 10 has by far more presets and a better way of rendering than the 9 counterpart. However, the post still does not state HOW to fix the bugs if you did download.
We are then greeted by repetition when I say that I found a fix, and the video can be seen above. It seems weird that I can go in and force the software to work in little under 10 minutes, and yet sidefx can not simply repair it, and allow the NON FOURM USER to download a fixed copy, rather than going on a hunt for a solution. (The daily build 10.0.613 has the necessary reparations with the exception of the permissions problem). Surely to god, if they are too lazy to manipulate the installer to ensure these files remain fully read and writable, it should be easy enough to include an Automator workflow that does the exact same thing…yes all Macs will have Automator!
So in conclusion, I simply state that the people at Sidefx are focusing on tiny problems, rather than realizing that most users can't even get their software to work on SL.
As a side note, most workstations have already upgraded to SL, and with Houdini being 64 bit ready, it seemed logical to upgrade to the new version in most cases (64 bit enabling use of more RAM, better hardware management etc.) Saying that I should remain in Leopard, or stick with the Houdini 9 is BS!
I'm sure Dreamworks and other companies just adore the idea of using outdated software to meet tight deadlines. That's like giving a teenager an essay to write with a low ink pen!

RatmannYeah…FLICKERING PROBLEM WOAH! That means fud unless I have the actual application working, which it won't cause of PERMISSION PROBLEMS WHEN INSTALLED ON THE ADMINISTRATOR and ALL OTHER ACCOUNTS (Houdini 10.0.430 and the MARKETED VERSIONS all suffer from making important directories that disable access to ANY account) as seen in my YOUTUBE video…
Did you two even bothered to look at this page [sidefx.com], before making your “$8000” purchase?
http://www.youtube.com/watch?v=v8O3KIPOoWk [youtube.com]
10.0.430 the publicly available release of Apprentice
MARKETED meaning all bundles that require money to acquire

It clearly hasn't been changed so non fourm writers can access the latest build and SEE the fixes! And, as emeek said, say I bought the $8000 version for my computer cluster at work for 3D modelling…now do you honestly think I am going to spend hours updating each machine on the cluster? Hell NO! Meanwhile if you got your asses together and started marketing the FIXED version, instead of sending the user on a SCAVENGER HUNT, the Houdini world at peace. Say I don't wish to join the fourms, I am STUCK WITH THE VERSION THAT DOES NOT WORK BECAUSE NO OTHER OPTIONS ARE AVAILABLE! This in my opinion is BS, and should be fixed…This is rediculous. And I love how the DEVELOPERS say the latest builds work on THEIR machines…NO SHIT THEY DO! YOU MADE THE SOFTWARE! So instead, what you are saying is that it's OUR fault that it don't work! WTF is that? It is YOUR fault for NOT PROVIDING A README or SOME OTHER DOCUMENTATION ON THE SITE STATING THE PROBLEMS AND SOLUTIONS WITH THE MARKETED VERSIONS! I MEAN sure, I can spend HOURS upgrading a cluster of computers, or IF I KNEW ABOUT THE PERMISSIONS PROBLEM…I CAN SPEND 1 HOUR FIXING IT! BUT NO! SIDEFX DOESN'T LET THIS INFORMATION BECOME VISIBLE TO THE PUBLIC, SENDING THEM ON A SCAVENGER HUNT!!!
GET IT TOGETHER!
STOP MARKETING FAULTY PRODUCTS!
MAKE THE DAILY BUILDS PUBLICLY AVAILABLE!
INCLUDE INFORMATION ABOUT HOW TO FIX THE PERMISSIONS PROBLEMS!
STOP POINTING THE BLAME AT APPLE!
STOP POINTING THE BLAME ON THE USER!
GET YOUR ASSES TOGETHER AND FIX THE MARKETED VERSIONS!
HAVE A PLEASANT EVENING!

Version: 10.0.430
My Process:
Open Houdini
Set a Ground Plane (RBD ready)
Create Sphere
Adjust Frequency to 10
Place Well Above Ground Plane
Create a simple Cube and shrink to microscopic size
Select Sphere
Go to Ridged Body Tab and choose RBD point object
Select Cube as shape and press enter
Go into AutoDOPNetwork and set the physics from RBD to ODE
Press Play Button
CRASH!
–Try it yourself

… cutting render times on ANY machine in half, or on an OCT core MAC PRO, by an eighth of the time!
Are you aware that Mantra is fully multithreaded, and the Houdini fluid simulator is partially multithreaded but also distributed over multiple machines? You just need to run on a commercial license of Houdini.
More info: http://odforce.net/wiki/index.php/HoudiniApprentice [odforce.net]
I realize that MANTRA is fully multithreaded, however when simulating RBD objects it utilizes only 50%

Am I missing something or is there some article on the Apple site that details that for a program to be “Snow Leopard Ready” it must take full advantage of ALL advanced new features? That seems like a very lofty and unrealistic goal to me.
No…See FCS3 is considered to be Snow Leopard Ready, although not actually 64 bit, it still utilizes full CPU and GPU capabilities.

I hope this works out soon.
Another PROBLEM that should be resolved:
CPU usage…on average, based on measurements taken on both of my machines, the app will only utilize 50% of the CPU on a Core 2 Duo Machine. This in a nutshell means that it is not SL ready, as it does not utilize the full power of your CPU, nor does it utilize the full potential of GPU. Thanks to the developer tools provided with SL, I am sure that this can be fixed, cutting render times on ANY machine in half, or on an OCT core MAC PRO, by an eighth of the time (Imagine simulating water in half the normal time…) To be fair, this is still a new technology, however to claim this app to be SL ready, it should AT LEAST support multi-threading to multiple cores, and GPU utilization if possible!!!

Well for starters, I installed 10.0.430 directly, without any of the predecessors. This is one problem, as the predecessors patch the problem, however the one available on the left hand side of the download page, does not. as for 10.0.463, so long as you have fixed the bugs with 10.0.430, it will function properly. But, if you install 10.0.463 without having any previous version of Houdini installed, or patches, then you still run into permission problems. The installer, to my knowledge, creates those directories by itself, so a simple tweak that tells it to grant full read and write access to every user, will possibly eliminate this problem.

As for permission problems, according to the Journal they have been fixed since 10.0.417.
No sir, actually this problem still exists as of version 10.0.430 that is available on the site (hence my guide located on page 4 of this topic). I have tried the new version of Houdini and can confirm that permission problems are still there.

Installed 461 and no more flickering. Thanks Mark!
Ok…can you please provide a download link? I would like to see if this permissions problem has been resolved…if not, I was wondering when it will be resolved, as I am going to assume many Houdini users are experiencing this problem.
Thanks

Good new! I have working! I don't know how to thank you for the best help service i've ever received! I just subed you're Youtube channel.
Is their any thing else I need to know?
Don't sweat it. This help will always be available for all Houdini users as well, as I am going to assume most of them are having similar technical difficulties when using Macintosh computers with Snow Leopard.
Enjoy Houdini my friend, and post some of the stuff you make.

Ok…I can service it remotely if you want…Just get an app called TeamViewer and I can basically walk you through patching Houdini…All I will need is your user ID and password if you set one, or use the default provided by the app…
User ID: ### ### ###
Password: ****** or (4-character code)
That will remove needless stress from your person…
PM me the details
