Resample Sop Node Default settings. Oct. 26, 2022, 4:38 p.m.

Hey there.

I hope this post doesn't sound like I am angry. Just a little frustrated after having had 2 hangups today due to unwanted behaviour.

I haven't made any form of RFE in years now so I am not sure of the process, but would it be possible to change the default behaviour from having it set to maximum segment length to max segments instead? The reason I say this is that it is not always the case that people work on small scenes. It always gets me hit in the but when I place it in a large scene and it cooks forever because by default it's set to 0.1 When working with units as large as 100000 or more, this behaviour often crashes the scene, or takes absolutely forever to cook. I would rather have a safe mode for this node that shows what it does regardless of scene scale ( even if the max segments are set to a higher value like 100 or 1000 and then adapt to my needs.

No node should ever crash/ or break houdini because the user is not working at an expected scale. This has bugged me for years now. It's just that today it hit me in the butt twice, and it is getting annoying.

I know I can set defaults, but that doesn't fix the issue at it's core. Every time I update workstations, change studios, get a new houdini version rolled out, etc. I don't want to have to keep track of this issue.

hopefully others agree.

Point attrib to Node name set. ( Python) June 1, 2022, 9:57 p.m.

Thanks guys.

So, for whatever reason using node.setName(str(someDeclaredVariable))
was giving me the following error:

hou.NetworkMovableItem_setName(self, name, unique_name)
OperationFailed:the attempted operation failed.

However, I did as hinsunlee suggested. I wrote str(someDeclaredVariable)) into the name section when creating the node and not as a separate line, and it worked out .

so what worked was changing this line

createGeoNode = createWorkArea.createNode("geo", "geoNode")

into this

createGeoNode = createWorkArea.createNode("geo", str(fullPathAttrib))


Point attrib to Node name set. ( Python) June 1, 2022, 3:14 p.m.

Hey there.

I have a question

1.) I am trying to take a pointcloud with a string name attribute, and then I want to create a geo node per point,
2.) extract the path attribute from the point and feed it into a parm on that newly created node
3.) set node name to the name in the attribute as well
3.) in python.

import hou

sel = hou.selectedNodes()

createWorkArea = hou.node("/obj").createNode("subnet", "workArea")

for node in sel:
    geo = node.geometry()
    points = geo.iterPoints()

    for point in geo.points():

        Path = geo.findPointAttrib("name")
        FullPathAttrib = point.attribValue(Path)
        createGeoNode = createWorkArea.createNode("geo", "geoNode")
        #############The line below is causing issues.

        AttribParm = createGeoNode.parm("some parm here")

So I got the parm set portion working, the creation of the nodes is ok. but the setting the names of the nodes not so much.

What am I doing wrong?

EDIT: I also tried this in the problematic node. didn't work either.

createGeoNode.setName('' + str(FullPathAttrib))

Any help would be appreciated.
