Hi SESI,

Linux Houdini 8.1.655

The COPY SOP doesn't seem to stamp strings. Is it a bug? I'm using stamps()

Simple example: place a FONT SOP, followed by a COPY SOP.

In the Copy Sop set “Number of Copies” to 5, Translate-Y to -2. In the Stamp Tab, turn on stamping and set key/value to “thing” and “blah”.
Then back in the Font Sop text-field set the following stamps() expression:
`stamps(“../copy1”, “thing”, “uhoh”)`In setting the Copy Sop's Stamp Value I tried a number of usual hscript tricks, like `echo “blah”` and evals(“echo blah”), run(“echo blah”), just “blah” and ‘blah’ and blah.

It doesn't seem to work. Also, the default string “uhoh” doesn't appear unless the variable name in the stamps() expression is made incorrect. Example hip file attached.

The Copy SOP only has float parameters for stamping.

Oh. :-) Thanks Ed.
Then perhaps the Example in the help/reference for the stamps() expression should be changed. Currently the example is:

Examples
stamps(“../copy1”, “name”, “defaultname”)

cheers,
ben.

Currently the only nodes that can stamp string values are the Copy Data DOP, and the Sop Solver DOP (which stamps the DATAPATH and DOPNET variables on the solver SOP, not on itself). But yes, the stamps expression example should be more clear about where that expression might be used.
