Hi there!
Do radeon cards work as good as nvidia consumer cards on windows, now? Or is nvidia still the better choice for houdini?
Cheers,
Marc

No, I don't think you're right, if I understand your question correctly.
Yes, rand() gives results between 0 an 1. It's just designed like that. A good idea, imho. Because you can just multiply or use fit-functions to have the desired value range. Just think of 0 to 1 as *percent*.
Rand() is a pseudo random function. If you feed it with the same seed value, it will give you the same result. This behaviour is essential, because the results don't vary if you run the animation again.
So, to achieve a result, that *feels* like it's random, you have to vary the seed value over time ($F is the frame integer, so it's unique for each frame - better use $FF since it's float), over the particle id ($ID) or something else. E.g. the object's z coordinate or any other attribute you can imagine.

Houdini Indie and Apprentice » what means bgeo?

It's the file name extension for houdini's native geometry file format. As far is I know, its name means Binary GEOmetry.
Do you just want to save out your simulation as baked geo? Then this node is the correct one.
Your question is not easy to understand. If that's not the answer you're after, please be more precise.
This may be a good start: http://www.sidefx.com/docs/houdini13.0/io/geo [sidefx.com]

Houdini Learning Materials » How to get paths to all parent nodes

I would do it in python.
Get the parent (and the parent's parent…) by refeeding the resulted parent node path into the next loop iteration until the result equals “/” (= root level).
Just append each result to a list and voilá.
If you just want the first 10 parents, you can add another break condition by counting the number of iterations.

Just lock the last sop by clicking the node's red flag (the second one beside the bypass flag) in the chain and delete all the other operators.
Or export a file and load it back in with a file sop.
If you just want to tidy up the look of your network, you can encapsulate all the sops inside a subnet - without loosing the history.

Houdini Lounge » Optional node auto-coloring

I think the auto-colored nodes should use low saturated colors by default.
So you can still use signal colors for specific and very important nodes to find them at a first glance.
BTW, coloring the wires could be handy, too.

I am not sure, if I understood you correctly…
As an alternative to restricting the number of used cores (in the mantra node, as you mentioned), you could switch the priority of houdinifx.exe-process to “lower than normal” via right-click the process in the task manager. All mantra.exe processes, started by this houdini session will inherit that setting.

I can confirm that this can also happen on 1-monitor configurations.
I remember that I also had for-each sops involved, whith the scene viewer pinned to upper levels (outside the for-each)…

Thanks for your input. That will do it for now…
Do you know any resources about how I can add new functions to houdini's scripting language, permanently and/or for the current hip-file only? I always wanted to extend it a little, but don't know where to start.
Cheers

Hi,
I don't know if I'm overseeing something very obvious here - sorry, if that would be the case…
How can I “rasterize” a float to have only a given number of fractional digits?
What I mean is an expression like (desired result is 9.12):
xx(2, 9.123456)
Is there something already available? Or do I have to build a function myself?
Thanks,
Marc

Um, well, that's exactly what I did. Thanks for that clarification! After I restarted houdini, the behaviour is as expected, again.

Apollogies, if I'm overseeing something obvious…
How is it possible to let an object recieve shadows casted by a specific object, avoiding self-shadowing. Right now, I am playing around with the shadowMatte material. Without success so far…
My goal is to integrate in post a new object into an already rendered sequence, lit by a sun light and a sky light.
I assume, this has to be done within the shader. But how?
Cheers,
Marc

Houdini Lounge » Where is the rusty metal material?

Could be worth a try… Thanks 12++
So, is there anybody with a h10 installation (maybe you?), who can give me a hip file with just the rust metal material inside? I would like to have a look at it. Unfortunately, I can't find my archived h10-setup.exe.
Btw: Why is the “Daily Builds” section so short, since the last month or so?
