HI
Since one or two version, I'v lost the linux-like behaviour of the middle clic in vex and python edditing where there was a buffer of the previously selected string. That was very handy.
I wonder may-be its dependent on the install or settings and I could retrieve may linux-like mouse?
Cheers

Hi
I like the houdini_launcher but since I use it I deeply regret not to have in my windows application folders the direct link to other applicationw like mplay, command line,geometry viewer and so on....
What is your view on this, and coul'nt we have the possibility to add them when we install through houdini_launcher.
Cheers

Hi
here I have an HDA with 2 outputs, one polygonal and one a curve. When I import tis HDA in Unreal 5.1 via Houdini engine, the curve does not come through.
I would realy apreciate if some Houdini to Unreal Guru could tell me why. I've reported it as a bugg to sideFx but I maight be doing something wrong, it happend before
Thanks for your help

cant find a solution on trying to output curve from an hda in unreal.
has someone encountered this error ?
and found a solution ?
Thanx alot
has someone encountered this error ?

Thanks tamte
Ok I get that its not a good idea, but.... it is working for createNode...
I'v tryed to call a kill conction on my HDA.module but as I call it from a python inside the hda it gives the same result
I will see if there is some other place where I could trigger this kill fonction. Somesthing like "on recook"
Any way thanks a lot for giving me a direction to where to look.
By the way, I'm not sure to undeerstand why it's a "bad idea"
cheers

Hi
How come I can create nodes inside an HDA with Python, but I cant delete them later ?
I need to dynamicaly create shaders on the fly, but need my material network not to get overcrowded with nodes after a few iterations. But I could'nt find a way to clean my network at the beggining of each new "cyle".
Any clue on how to workaround this annoying "cannot delete nodes while cooking" error?

Hi
Is tehre a way to keep initial orient on "attach to geomeetry" vellum cloth point. It seems that its only transform constraint and no rotation constraint. I would like it to behave the same way as vellum hair "pin to target" points.
in the mp4:
in blue cloth with attach to geo
in orange hair with pin tot target
stretch stiffness and bend stiffness are the same on both.
Or maybe a workaround?

Hi, I need a PDG master for this one.
Let say I want to wedge an attribute with three values driving diferent versions of my sop network.
For each version I want a second wedge to process some assets, but I need different number of work items on this second wedge depending on the version.
I explored many ways to generate or cook these twoo wedges but I always have the same number of work items for each version on the second wedge depending on the selected work item on the first wedge at the time I re genrate and/or cook the top network.
Any idea ?
Thx

Hi
Does someone knows if it is possible to have an hda to generate kinefx and geometry inside a HDA for unreal and have them both working in unreal, skinning and all ???
And of course if someone does, it would be nice to know how it is done.
The doc for Houdini Engine for Unreal is not clear about this.
In the output section it first says that the only outputs suported by Houdini engine for Unreal are:
Houdini Engines for Unreal currently supports outputting four types of geometries from Houdini Assets:
But in the skeletal mesh section you can read:
thanks for any help.

Hi beratna
I do not have the string memory buffer on the middle click in vex or in text pannels anymore.
Do I need to set up something to have it back ?
Is it a normal behaviour ? That bould be unfortunate;
Had someone encounter the same issue?

Hi
Here a simple setup to wedge some parameters. Everything works perfectly, wedge, open gl, image magick, ffmpg... But when I want to delete the no more usefull images genarated by the fetch rop gl , I cant find an expression to retrieve the path from the fetch rop gl. Of course I could manualy point to the file path but I would like to make it procedural, the idea is to make an hda to automate wedging process.
Thanks

Hi
I have this very simple setup wit a flip sphere falling. When I enable viscosity on the solver even wit very low viscosity value on the flip object as one in this example, the fluid get struc in the air and does not keep on falling. As you can see in the mp4, first part without viscosity , second part with.
I'm probably toing somthing wrong but I cant figure out what ?
any help very appreciated

Hi,
Here is a situation:
I have a simulation, let say particle simulation, fairly long one.
Then I have a render with the same amount of frames fairly long one too
I would like to setup two rop_fetch in top and have the fisrt frame of my render execute when the first frame of sim is done, but I cant fin d a way to plug them other than each simulation frame generate all render frame.
I tryed diferent partitioners with no succes and I could'nt find a wéay to have the dependency going frame by frame ...
any clue? Thanx

thx
