Hello
We are using package manager to distribute our Unity Content. We are hitting a brick wall when trying to deserve HDAs due to the read only nature of Unity Packages. Just out of interest is there any thoughts or ideas for circumnavigating this issue?
many thanks

Hi there
So I have an HDA with a python function call attached to a button paramater as a callback. In Unity this button works if I hit teh button in the GUI
Is there a way to call the same function via the API in Unity or a nice way of pushing the button programmaticlly?
I could not find any mention of buttons in HEU_ParameterUtility
many thanks
Sam

hi all
i am trying to get duck typing behavior in vex where I can scale a space seperated user selection of point attrs regardless of type
this wrangle code is working but it relies on predefined variables and would need extending for matrices and arrays ect
anybody have a nicer solution?
cheers in advance

string attrs[] = split( chs("attrs") ); string pattrs[] = detailintrinsic(geoself(), "pointattributes"); string a; string pa; int type = 0; int typesize; int tmpi = 0; float tmpf = 0.0; vector tmpv = {0,0,0}; foreach(a; attrs) { foreach(pa; pattrs) { if( pa == a ) { type = pointattribtype( geoself(), a ); typesize = pointattribsize( geoself(), a ); if (type == 0) { tmpi = point( geoself(), a, @ptnum ); setpointattrib( geoself(), a, @ptnum, tmpi * ch("scale"), "set"); } if (type == 1) { if (typesize == 3) { tmpv = point( geoself(), a, @ptnum ); setpointattrib( geoself(), a, @ptnum, tmpv * ch("scale"), "set"); } else { tmpf = point( geoself(), a, @ptnum ); setpointattrib( geoself(), a, @ptnum, tmpf * ch("scale"), "set"); } } } } }

my example above would remove 20% of points
using a modulus is fine if you want to remove a simple amount ie half %2, a third %3 ect
I had another go and realised that to use a percentage instead you could use the following snippet:
int percentage = 75;
if ( @id % 100 < percentage )
{
removepoint( geoself(), @ptnum );
}

in a attribute wrangle running on points you can use:
int modulus = 5;
if (@id %modulus==0 )
{
removepoint( geoself(), @ptnum );
}
the code above is tested
int modulus = 5;
if (@id %modulus==0 )
{
removepoint( geoself(), @ptnum );
}
the code above is tested

I love the new loops workflow really fast and flexible to work with
however i cannot stand the new convex hulls they drive my OCD to distraction
what I wouldn't give for a square bbox (not a subnet) version to keep my networks tidy
as it stands I have to put nulls in the corners to make a quadrilateral

hi pezetko
thanks for your reply
been having a look at this and i can't get the functionailty i want
it says in the docs:
This object is “read-only”. To create or edit connections, use methods on the node, such as hou.Node.setNamedInput, hou.Node.setInput, hou.Node.setFirstInput, hou.Node.setNextInput, hou.Node.createInputNode, and hou.Node.createOutputNode.
There are no setter functions available on this class that i can find unless i am missing something?
Just to reiterate - my issue is that I want to create connections based on names not indices. There is a helper function on the hou.Node object to convert input names to indices but not output names to indices - i require both
does anyone have any examples ?
any help would be most appreciated

hi dedks thanks for the post
I did have a look at this before - isn't this just for existing connections?
Maybe I have the wrong end of the stick
do you have any examples by any chance
I want to connect multiple outputs from a vop to multiple inputs of another vop by name rather than index
many thanks

Hi there lovely community
I'm wiring our ubershader and am having a bit of a snooze fest wiring uploads of inputs in vops
I have a good naming convention so should be able to script it but am a bit baffled by the
the relevant functions:
outputNames - returns a tuple of connector names
setInput - requires indices
inputnames - tuple of input names
inputindex - gives an index from a name
there is no outputindex function - doh!!
not sure how else to do a lookup by name as i need the relevant output index for the setinput function
anybody have a workaround / alternative method for this?

i recently had a thread with a similar issue
https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=42090&highlight=detail [sidefx.com]
as a temp solution:
unpack the geo
attributes on the transform in maya come through as detail attrs
attributes on the shape come through as primitive attrs
you can get to these without unpacking with stylesheets

don't want to hijac such an important thread
is there another somewhere with more info (and hopefully examples) of the @group_foo syntax in use?

hi rafal
thanks for your examples - very informatve
two points from my end:
1) - @Struct.member syntax is great to know -
does the unexpected behavior in the efficient_modify method happen outside of the local function scope? - ie outside the current vop - if so this is not prohibitive in this case as it is my last operation - i will try to test tomo
2) in my case I am actually trying to dynamically replace a different elemnt in my struct by index. ( all elements are of uniform type vector 4 so type is not an issue). Any vop method would require a prohibitive amount of switches as i could not find a single inut to many outputs switch
Otherwise in vex is there a way of getting and setting the value by index value? I realise the @Struct.element syntax would not work unless i could maybe using hscript `expressions` ? ie @mystruct.`$myindex` and the form @mystruct.1 was valid?
is that supported?
