I'm working in Unity trying to launch Houdini with the HOUDINI_PATH and HOUDINI_PACKAGE_DIR value set,I wrote c# code to set the env variable before launching Houdini,but after the setting,Houdini can't be open,
so,I am trying to set it in the computer,not by code, just to check out why Houdini can't open,
and now,if I add HOUDINI_PATH with value like C:\a\b\c ,it shows error:

ERROR: Couldn't open resource file "resources" (No such file or directory)

and if I add HODUINI_PACKAGE_DIR with value like :C:\a\b\c\package ,Houdini does not appear at all.
anyone can help to tell what is the standard about it.
thanks.

just read the document again,
turn on "editable nodes tolls enabled" on "HDA_Data" node is the right way,but what i did it wrongly is that I set the paint node to be the editable node,it should be the "output0" node inside paint node,and the paint node should be unlocked.

Hi,josyzhaocn,
have you fixed it?
I am working on unity 2020.3.33f1 houdini 19,and I have the same problem,
for this version,there is no "enable editable node tools" on the hda node,but there is a "editable nodes tolls enabled" on "HDA_Data" node.I tried to enable it ,but still no UI showed out.
In my hda,there're "attribPaint" and "curve1" nodes which could be edited.

http://forums.odforce.net/topic/26288-quadro-m4000-driver-problem/ [forums.odforce.net] maybe this help a little if you are having the same problem with me.
And,I have two machines and one monitor actually,I use a switcher to switch between them,for my old machine (quadro k2000),to make sure the switcher works,I must update to new driver which cause problem to Houdini,but with old driver where Houdini is ok,the switcher does not work well. Houdini crash every time I switch.So,problem is also about Houdini.

I have this card as well and have to admit, I have more than a few viewport problems. Houdini's viewport has always kinda been a little underwhelming, and I always kinda chalk it up to that. I have only had this card for about a month, but did a full driver re-install the other day. I am not sure yet if has helped really.

I always feel like there is some opengl setting that I am missing somewhere in Houdini

Hi,guys,

Does anybody use quadro m4000? I just bought a new machine with this display card,but there is some problem with pyro fluid display.

Houdini does not crash,but the display is no correct ,the color ,the shadow,you know,I believe it's about the driver.

I am working on windows 10 64bit,and I tried a lot of different version of drivers downloaded from nvidia,but none of them works.

Anybody use m4000 and has gotten the good luck?

Thanks.

Peng.

Hi,guys,
I am trying to build a digital asset here,It's a asset inside shader,I mean it's at vex builder level.
And now I want there to be some parameter which link to a rotation of an object level camera.
Because the rotation keep changing,so I must like write a expression for the parameter of the DA.
And here is the problem,it seems that I can't write expression at vex builder level,it does not update.
I know I can promote parameter to shader level,but I do want to keep it at my digital asset which is at vex builder level.
So,how can I get that changing data and make it work for my digital asset?
I did some test,maybe someone can check my test scene(houdini14) and help.
Thank you guys.
Peng.

tamte
for hscript arguments should be in variables
$arg1, $arg2, …

wow,it works now.
Thanks a lot.

Hi,guys,
I am creating a digital asset now,and i need to write a script to do things like:
node=kwargs
node.setParmExpressions(“tx”:'point(“somenode”,0,“P”,0)')
But i need to do it in Hscript,not python.
I know how to set parameter in Hscript:
opparm digitalAssetitself tx ‘point(“somenode”,0,“P”,0)’
but how should i get the digital asset itself in Hscript?
Thank you guys.
Peng.

thank you,i will try.

hello guys,
i am doing flip water in dop, now ,i want to group the water to like 10 groups randomly,and then i can give them different force,i kown how to randomly group points in sop,but in dop,how to do it?
thank you.

this seems to work.
i am new to houdini,do you think it's ok?
it's houdini12.

hi,
Does anyone use houdini with a display card quadro 2000?
in my case,windows 7 + Houdini12 + quadro 2000 =crash
a windows 7 message come out by saying this:
quadro 2000 display dirver stopped responding and has recoverd
and houdini12 says openGL error.
other application do not have this problem,just when i am useing houdini12.
i tried different display drivers,i don't think it's the driver's problem.
and i searched google,some other guys have the same problem,but they have it when they are playing 3d games.
this problem just happen on window vista and 7.
maybe i could turn off something which i don't konw in houdini,and i can keep using it.
any help?
thank you very much.
