I have another question but it is about FINITE solver. For days I have been tryng to figure out why my simple finite simulation is so slow, and I have been trying to optimize this optimize that, and today I checked the core usage and I can clearly see that finitesolver uses one core usualy above 95%. Is multithreading not implemented yet.
I am on centos and H 13.0.288.
I was thinking to use this for production for a really cool movie on a giant demolition scene( not for demolition itself but for other elemnts on top of demolition)

380mb is ok man, try 3.8gb per frame . Also don't forget some of the fields are and can be useful later on, like surface velocity, etc, some of these fields are used for whitewater creation.

I am pretty sure this can be done. I think I would be able to help you if I could only fetch the glue network visulisation geometry from DOP instead of RBD Object, just could not find the name to fetch. Anyone ?

pusatWe came up with a similar idea, to run an external python script per for each and to write out a TXT file, we will try it tomorrow, will update the info here if we succeed
I think you can do this using the Python SOP, creating the file before Foreach and writing to it inside the Foreach.

My guess is you have an AMD card. I and many other had the similar issue with AMD Radeon line, my one 7950 in this case, both on windows 7 and Ubuntu 12.04 with the latest drivers this glitch happens, it doesn't happen when i use viewport gl2.1 .
I never saw this happening on consumer or pro Nvidia Cards, did not have a chance to work on firepro with Houdini so I don't know about that yet.

Hello all, I am using a foreach setup manipulate geometry for every piece that is coming from a different department, , when I make a test region to work on around hundred pieces , the speed is fine, but I will be handling several thousand pieces, is there a way to visualise a progress report or to dump out a txt file for each piece number processed.

Although, I don't know if i can apply with my lil python knowledge. If it is the right direction I can ask my colleagues,
Thanks

I have the Adobe Creative Suite on it, and a lot of other software as well.
Well, it looks that he uses more than just one program in Windows. So switching to Linux just for Houdini for me would be a “no, no” option.
As for Linux, don't get this childish ditro that is called Mint. It's for babies that are afraid of serious Linux experience. Use OpenSuse.
Wow man, that a bit harsh.
I use computers since I am 6, hell i learned the alphabet from a C64, but still find my way easier on windows than , linux, yes I have dual boot also, ubuntu 12.04, I do all my overnight sims and renders on linux, and I game on windows .
But not everybody needs to be a linux wiz, even thou most of us are FX TDs, we still dont have to know the OS to the bones.

just the answer I ve been looking. I have been having a problem on a Building Collapse RnD, I simmed the main floors and columns, and then made another DOP where I put in the cached simulation as passive rigid body with concave collision, and when I turn on the visibility for collision under bullet data, it seems fine. But when I ran the simulation, some bricks and random stuff laying on the ground penetrate through ceilings ?
I am not sure how to fix this. or where to look ? any ideas?
Also as far as I read SDF collision does not work with Bullet, is that correct ?

update,
The problem exists only in Windows but unlike hogging the machine to a halt, the simulation continoues, but you do start hearing the HD going bananas and eventually Windows returns not enough memory error, maybe crashing Houdini along the way, happened on the 192GB ram machine with 50 mil particles.
I tested the same scene on my Ubuntu, another scene with 25mil pts this time, simulation starts around 6gb ram usage and when the collisions happening, it peaks around 20-25 gb usage but I still find this amount of ram usage abnormal compared to previous versions or what Naiad was able to do with 8GB ram .
So far however at work and at home on linux this doesnt seem to be a big issue, but on windows , flips are a no go in my particular situation.

Only for Houdini, you can get Dual Xeon machines, which will serve you much better for Houdini, you will get almost double the speed compared to single CPU for the same price you would pay for a MAC PRO, dual Video cards will not give you any advantage inside houdini, AMD firepro drivers has something called Crossfire Pro , but I am not sure if Houdini can take advantage of it. Anyway, Houdini is the master of FX, thus better have two cpu then one, as far as I am concerned Apple build this machine for OpenCL video editing.

Maya sometimes doesnt understand if some extra attributes are carried inside the ABD and makes the wrong connections, if you open you ABC in hypseshade or node editor to check connections you will see what I mean, One way to fix this without reexporting with cleaned attributes is to reconnect the mesh inside maya again,
I had the same issue exporting the ocean surface with cusp and maya was trying to connect the cusp attribute as mesh and was giving the same error.
If this is not clear explanation I can make some screencaptures if you want.

Hi, can anyone answer me if Houdini Composite can composite deep rasters from both .rat or exr2 files, the reader seems to fail to load deep image files but dsmflatten seems to load them correctly.

I suppose this issue applies to other tools in Houdini 13 also, like Pyro, RBD multisolvers etc, on windows, please confirm.

Possible Memory Leak
H13
I seem to be having a very strange problem. Regular ocean surface 60 by 30 and 5 depth , passing velocities to a flip tank with similar size. Its like Igor Zanics coast beach Flip simulation
I have somehow detailed collision mesh on one side with like 200K faces and with a voxel size 0.1 it gives me sufficient detail almost 3mil VDB voxels. So VDBs as static collision( no deforming or translating collision objects here)
My machine has 32 gb ram and I am running out of memory with only around 20-25 mil points, which I believe is low as far as I can remember, Many videos on Vimeo are doing much more points with less ram.
The funny thing is I tried the same simulation on another PC with 190GB ram and 50 million particles were just passing 100 GB ram usage,
The other thing I noticed is that, the ram usage just continues to increase and even triples itself over a period of 500 frames, however the particle count pretty much (or the file size) doesn't change so much at all.
Please help me out here. I am about to reinstall a linux distro to see if there is sth wrong with my windows

I am afraid cinebench wont be a good comparison tool for Houdini performance, I have been complaining here on the forum how bad the performance of HD7950 3GB card has been for H12 and 12.5 and meanwhile how the performance in maya was so much better. Well currently the same card is flying inside H13 and is considerably faster than in maya in high poly meshes.
I did the cinebench R15 test on this card with HD7950 3GB and it gives me 109.31fps , however I am certain you will have a better experience inside Houdini with your card.

I have the same issue with my AMD HD7950 on both H12.5 and H13 and at work I have GTX660ti and no such issue.
That's strange behaviour, I was testing 7950 in Linux, Windows and OsX and no issues. The only time I ever saw text garbled was with 2 monitors one being driven by AMD and the other by Nvidea, then draggin windows from AMD to Nvidia
Hmm I am also on Dual Monitor, but same card on windows

you can also try , deforming your mesh again with another ocean deformer with bigger swells.
