Hi,
is there an equivalent for h-script's padzero in vex (attribute wrangle sop)? I couldn't find anything related in the docs…
Thanks,
Marc

Tested 705 and 633. Crashes on windows (at least for me).
Build 733 works again. COPs in general feel way more responsive, too.

Thanks Konstantin,
I am trying to narrow it down. Did you try it with a file sop plugged in? I just realised, that it works for me, when I use e.g. a color sop as input. Connected wit a file sop (even with the standard butterfly pic), it's crahing houdini (windows). I'll try other builds…

Is the scale COP working for anybody of you in the past few builds?
Wanted to be sure, before I report a bug…

You can use $F in the filename.

Share your file and we can have a look.
Just a guess:
Filename of the model is set to tree$F.obj
($F is a global variable holding the current frame number.)
So when your are on frame 1, it expands to “tree1.obj”
The error states you're doing stuff with a timeblend sop. Maybe the file-sop is evaluated at another frame number than 1, so that now the file-sop is pointing to a non-valid filename (e.g. tree2.obj)?

Technical Discussion » What's the purpose of the NULL node?

Yes it is. And if you give it a name like OUT (in UPPERCASE), it will be automatically sorted at the top of listviews.
So if you're want to reference it from somewhere else it's quite convenient. E.g. if you browse for this null node because you want it to reference it from a object merge.
Please have a look at the new Output SOP. It's quite new and even a bit more convenient.

Try wildcards.
E.g. * (all groups), Object* (every group starting with “Object”) or ^myGroup (all except “myGroup”)
And there's much more you can specify. Have a look here (lower section): http://www.sidefx.com/docs/houdini/model/groups [sidefx.com]

Thanks guys, I'm aware that consumer cards are a game of chance with houdini. To be more precise, what card would you buy if you could not afford a pro card in terms of driver stability…
In the past I was under the impression that (concerning houdini) ati consumer drivers are less reliable than nvidia's. Would you affirm that?

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

Houdini Learning Materials » rand() function
- bollili

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
- bollili

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.
