Hey guys,
I'm wondering how to sim particles along surface? I mean something like in Maya when particles are using UV coordinates to move from 0 to 1, in U or V direction.

Hello everyone,
I'm trying to convert HDR to RAT format but I get this error in command line “Can't create output file fileName.rat”. I run Command Line Tools as administrator.
Also I've done this in mPlay and it works perfectly(with limitations)
Windows 8.1
Houdini Apprentice v13.0.570

Thanks for your reply. In my mac it works perfectly. I guess it is some settings I have in my windows version.
I know what does resize node. I need entire fluid container because I'm using it to drive particle simulation.
cheers

Hello everyone!
I have pop network and I would like to kill particles by their velocity. I've connected kill pop but I don't know how to define the rule. There should be something like v< 1,1,1 but this does not work

Most of the time minimizing Houdini window, changing focus, repeatedly tapping ALT and ESC escape keys in no particular order - helps. Sometimes though, I need to restart Houdini.
This helped me! Thanks!!!

It sounds an issue that others have also run into:
https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=34179 [sidefx.com]
Until a solution is found try the New Scene tab. That will create a new viewport.
Thanks! I'll give it a try.

Hope this will be fixed soon.

It's Houdini apprentice latest build. 13.0.509
I can't move persp and can't select anything but panels remains active. I can edit/create nodes.
This occurs mainly when I'm trying create/edit curves.
One more thing. Sometimes whole interfaces of houdini converts to viewport navigation area. I mean even if my mouse is outside of viewport I can tumble, dolly and track camera so this way all panels are inactive.

Hey guys,
Sometimes(at least couple of times per day) my viewport is blocked. I mean all panels are working except viewport. After trying different key combinations it freezes definitely. Only close/minimize buttons remains working.
OS - Win 8.1
Graphics - nVidia quadro k2000(340.66)

It is so difficult to print out randomly generated numbers?
Or maybe I should read Houdini's documentation?

Hey guys, actually what I need is a something similar of Maya Script Editor output window. E.g. output values of rand() function per frame. In Maya it would be :
float $sphereTY = pSphere1.translateY = rand(3);
print $sphereTY ;

Thank you for your reply! I'm sorry, it was syntax error I wrote. What a shame ops:
The variable name was incorrect – “customScaleX”, and should be “customScaleY”.

Hey guys,
I just start to learning Houdini and like other newbies have a lot of questions without answers.
So, I have a grid and object randomly placed with scatter node. In the stamp tab of copy node I have created a variable - customRotation with value - rand($PT)*360 and use it in the rotation Y ofthe translate node - stamp(“../randCopyNode”, “ customRotation”, 0) and it works perfectly. Now I want do the same with scaleY channel. I create customScaleY variable with value rand($PT) and us it in the same translate node in the scaleY channel -
stamp(“../randCopyNode”, “ customScaleY”, 1) , but nothing happens. If I change a value 1 to other random value the objects scales using this input value, no random scale is happening. What I'm missing? If I understand correctly, rand($PT) gives random value between 0,1, so why scaleY don't understands it?

Just noticed that if I change the primitive type to polygon it works fine.

Just for fun I've installed houdini on my MacBook Air(2011) and it do this operation perfectly!!!

Hey guys,
just started learning houdini, so maybe I'm asking very stupid question .
So please, be more patient with me.
Houdini interaction is very slow on my PC. For example:
I have created a curve and box object. Then I assigned to them Sweep and houdini duplicated the box along the curve. Now I want to change some parameters of Sweep. Trying to slide the slider of Scale, Twist or Roll but slider slides very slow. There is about 20-25 instances of the box on the curve.
Is this normal? Generally I use Maya, but in Maya such simple operation like this is not so slow.
I'm using windows 8 x64
Intel - Q6600
GeeForce 560 Ti
4Gb RAM
As you can see my machine is not so bad for such simple tasks(if it is so simple ).
