No printf() in volume wrangle?

[SteveNi]

Hi

This may be really stupid but I was working on a volume wrangle, and I noticed that the printf() function does not work on this kind of wrangle node...

Is it just me or am I making some kind of stupid mistake?

 

In the pic the node to the left prints nothing, instead of the node of the right (wich has the same code), wich actually prints "Hello" to the Houdini console.

I think you need a volume attribute to iterate over i.e. this works (if you bind to density for example):

printf("%s\n", "hello", @density);
