Hi

I'm going through Lesson 6 last example and has a question.
https://archive.sidefx.com/index.php?option=com_content&task=view&id=2186&Itemid=361 [archive.sidefx.com]

also attached the screen shots of the tutorial and mine.
In his setup he added “attribute transfer” in POP level. But in houdini V15, you don't have it in POP level.

What do I need to use instead? I tried “POP attribute from volume” but no luck. As you can see my spheres turn into black instead of getting red color attributes from the box grid.

Any solution?

This has been asked and answered a few times before, quick search would have found that.

Nevertheless, I didn't like any of the other answers, so I made my own.

Hey SideFx folk, maybe its time to do a re-record of some of the older stuff? Or at least take them down temporarily until they can be updated? All they do is cause confusion.

One more question.

I added “POP Group” with rule “@Cd.r < 0.5;”. But as you can see it doesn't work. In geometry sheet everything is still 0. What did I do wrong?

When you make the POP Group node it has “ingroup =” already written in there, you need to keep that. This should work:

ingroup = @Cd.r < 0.5;
