New For Loop and iterating index

[Pancho]

Since the Loop in 15 seems to be new, how can I use the iteration number (the x in For x...) within the loop? What's the name of this attribute?

Cheers

you can use various metadata detail attributes from Block Begin when in Fetch Metadata mode

Thanks! I'm able to display the Iteration number like in the video as a font. But how do I use it in a transform node? I tried $ITERATION and the detail(.... approach. The node always turns red. I also tried it with a custom attribute. It doesn't work either, though $CLASS works. I ensured that the attribute is in the same context (point or primitve). Nothing. $CLASS works, but $AVGDST (avgDst is my custom attribute) doesn't. Couldn't find any tips or tricks so far. What I need to do is make transformations on a per primitive basis.

P.S.: Thanks for the video link!

O.k., I managed to solve my transform problem. At least with my custom attribute, since it is a primitive. Found one of Peter Quint's videos.

To use my attribute I need to type in prim("../nameOfTheNodeBeforeTheTransform", $PR, "avgDst", 0). While this might be verrrrrrry logical for a programer, it feels more than complicated, especially in the small transform entry field.

So, how do I get the iteration into the transform? Guess the formular will be similar, but what kind of object is Iteration? Definitely not a point nor prim.

If you really need the variable name, copy the iteration attribute to your main SOP tree using an attribcopy SOP and then set the local variable in an attribwrangle node, set to "Detail" mode.  Use this code below:

// Probably set it to be "ITERATION" instead, but if you
// want to replicate the old behavior you could do this...
addvariablename(geoself(), "iteration", "FORVALUE");

getting the metadata using detail() should work

can you post your file?
