Hello all,

I'm trying to pass detail string attribute with edge pattern (p1-0 p2-3 etc.) to group field in dissolve node, but it doesn't work. Anyone has an idea why?
Edit: it works if I just manually copy and paste the pattern string from detail string attribute I've created previously.

Hi
Wouldn't it be easier to do this with a group?

-b

There are two common languages in Houdini, VEX and our Expression language. The backticks in the group field are invoking our expression language. In the expression language, there are two named functions to get detail attributes, `detail` and `details`. The first returns a float and takes an index into the attribute (so you can get components of a vector). The second returns a string and has no index.

Thus, there are some changes needed
1) A terminating backtick.
2) Use details, not detail.
3) Remove the 0 parameter


VEX, OTOH, shows up in Wrangles and the Attribute Expression node. It also uses detail to access detail attributes, but because VEX can overload on return type, there is only one version that works for vectors, strings, and floats.

Thank you, that's an interesting solution, though not exactly what I was looking for. But definitely worth knowing.
