Quick question, does Houdini Indie support loading .hda and .hip files?
I sell a .hda file but am unfamiliar with Houdini Indie and was wondering whether Houdini Indie can indeed load .hda files (same for .hip files).
Many thanks
Luca

Technical Discussion » dop pop attributes used by the solver to compute movement?
- lucavfx
- 29 posts

Hi, I was wondering, which pop attributes does the dop-pop solver uses to compute movement, also what's their mathematical relationship?
I've got so far:
v
force
targetv
airresist
the reason is that I'm not sure about the targetv-airresist force v interactions and I'd like to build a boids based crowd system and mix the use of pop fields and pop wrangles where I further manipulate v directly.
Many thanks

Many thanks for the useful pointers.
After trial and error I found out what I was doing wrong:
When duplicating the nParticle transform-shape the new nParticle shape was left without a nucleus solver.
Attaching the newly created nParticles shape to a new solver did the trick.
Many thanks

awong
The Maya plugin imports the Houdini particles as a standard Maya nParticle, so Maya's built-in nParticle cache would work on the imported particle. This essentially converts the .bgeo cache into Maya's own caching format. You can then attach Maya cache to a nParticle without needing Houdini Engine.
Note that when you use Maya's nParticle cache to cache the Houdini Engine nParticle, Maya will likely print out an error at the end saying it can't attach the cache to the nParticle. This is because the nParticle is connected by Houdini Engine. The caching has actually been completed at this point, so it's safe to ignore the error.
If you have custom point attributes on the particle, Maya would also cache them. However, when you attach the Maya cache onto a nParticle, you have to manually create the equivalent per-particle attributes on the nParticle. Otherwise, Maya wouldn't read in per-particle attributes. The easy way to have all the per-particle attributes imported is to duplicate the nParticle node that was created by the Maya plugin, since that nParticle node contains all the necessary per-particle attributes. Then, attach the nCache onto the duplicated particle.
Hi Andrew,
I followed your instructions to the letter, the nparticles cache is created on disk,
however upon attaching the nparticles cache to the duplicated nparticles transform node nothing appears when scrubbing in the viewport. I get the following warning I suspect might be related:
// Warning: file: CProgram Files/Autodesk/Maya2018/scripts/others/doImportCacheFile.mel line 99: Channel names did not match selected objects. Using channel houdini_engine_particles_v0011_0Shape_id on object houdini_engine_particles_v0011_1Shape. //
I'm on windows7 maya 2018, houdini engine 16.5.405
Many thanks

Hello,
Support for Python 2.6 was dropped for Windows since Houdini 15.5 was first released. This was done in order for Houdini to support the Visual Studio 2015 compiler.
Cheers,
Rob
Thanks, I wasn't aware. I ended up using an earlier build which supports both 2.6 and 2.7.
Best

Hi,
I can't find hython 2.6 in 15.5.632 and 15.5.773 (windows 64bit), has it been removed in recent builds of houdini?
changelog doesn't seem to mention this
Many thanks!

Update:
I passed the overridden variable HOUDINI_OTLSCAN_PATH by adding it to hq_sim and I can see it is set correctly in the client -as seen from the client properties log- however the client doesn't load otls from ~/USERNAME/houdini/14.0/otls

Hi,
our hqueue clients don't inherit the environment, espevially the otl paths.
i.e. otls stored on ~/houdini14.0/otl are not made available to the client.
I'm having a look at the hqueue docs but can't find anything regarding this. Also manually adding the otl_scan_path variable in the hqueue rop and submitting a job doesn't seem to pass the variable to the client on the farm.
Is there a way to configure hqueue so that clients would launch a specific wrapper? or simply inherit the current environment including otl_scan_path?
Thanks for your help!
LL

we're on linux centos and h14

Hi,
i noticed a memory footprint difference running the same hip file on win7 ultimate sp1 64bit and on centos6 64bit.
it's a heavy flip water tank simulation running on houdini 13.0.314, i think it's an example file straight from Jeff.
on win7 the simulation starts at 8gb of memory and goes up to 16gb at around fr50 ending in disk swapping.
on centos its stays steady at 8-9gb of memory throughout the timeline.
The centos6 workstation comes with 24 virtual cores and 48gb ram meanwhile the win7 laptop comes with 8 virtual cores and 16gb ram, so i admit a certain difference in hardware.
what do you reckon might be the cause for a double and increasing memory footprint on win7?

speaking of the masterclass,
Jeff a some point walkthroughs a collapsing building hipfile he previously built ( rbd + debris + smoke ). Does anybody know where to retrieve that example?
Also, he briefly mentions a more complex constraint network used in a falling domino of bookcases and books, but can't find this example either.
thanks for your help

Thanks Symex!!!!!
this is probably the most useful piece of information I gathered in a long time
and what would be the equivalent of pythonrc.py for hscript?
would that be houdiniX.Y/scripts/hscriptrc.cmd ?

Hello,
Two quick questions:
Where do you store a library of functions and how do you tell houdini to load them at startup all the times? (hscript or python, doesn't matter)
Also, what would the suggested method be for running a function every time a hip file is loaded/saved ?
Thanks a lot!

Hello,
I was wondering if I'm right to assume that on Windows the only way to compile dsos seems to be purchasing a full version of MSVC++ ?
Are we absolutely sure there is not another way, possibly freeware, to compile on windows7 win64 H11 nodes?
(I'm just throwing it out there that tutorials on how to compile 64bits using MSVC++ Express exist but perhaps they are not tailor made for the Houdini HDK to work)
Thanks

Hello there,
I was planning to write a maya plugin for reading/writing caches and I was thinking of using the .bgeo houdini format for this.
Is the .bgeo format definition available and… has a maya plugin (similar to the houdini file sop node) been attempted by anybody already?
Thanks

You could try running Houdini 9.1.232 from the daily builds section. The version you are using is very old

How can I reach the daily builds section?

Hello,
I'm running houdini 9.1.179 apprentice win32 on my dell m6300 laptop and it is very slow, it takes seconds to create a point sop for instance.
The whole software is very sluggish and I was wondering what I got wrong :cry:
I've got a fairly powerful system (dual core 2.4ghz, 4gb ram) and I'm running windows xp 32bit sp2 with all updates and no bloatware whatsoever.
I'm running a nvidia quadro fx1600 512mb with dell's forceware 156.19.
Help
Thanks
