Two Heightfields in OpenCL April 6, 2025, 4:20 a.m.
Hello,
I think that you could do this by changing the name of the second heightfield to something other than "height" using a Name SOP before reading it in OpenCL SOP. This way you can get two different names for bindings.

Houdini package expressions not working Dec. 5, 2024, 10:03 a.m.
Robbert
it does not seem to work if I try to compare with any self-set environment variables inside of the package file
Self-set environment variables work well for setting a value, like :
{
"env": [
{
"MY_BROWSER_PATH" : "C:/Program Files/Google/Chrome/Application/chrome.exe"
},
{
"HOUDINI_EXTERNAL_HELP_BROWSER" : "$MY_BROWSER_PATH"
}
]
}But they don't work for package expressions when set within the same package file, and have to be set prior to scanning this package file. You have to set
SOME_VARin a previously loaded package file or in system environment variables before starting Houdini (and called with $prefix, without single quotes '') :{
"env": [
{
"MY_BROWSER_PATH" : "C:/Program Files/Google/Chrome/Application/chrome.exe"
},
{
"HOUDINI_EXTERNAL_HELP_BROWSER" :
{
"houdini_version == $SOME_VAR " :"$MY_BROWSER_PATH"
}
}
]

I think this is because a number is expected, not a string.
The expression syntaxe actually expects string values.

I am actually surprised that it managed to output something here, because the syntaxe for
Using braces should output the expected RGBA(0.5, 0.5, 1.0, 1.0) value :
