I have a hdaprocessor that generates something according to the given random attribute. I want to get attribute and the next request will be used to sort the results, for example split @attribute>=2. I try to use attribute but I can only use only those that are in topnet or created in wedge.
What is the easiest way to get attribute from generated content.

Do you mean that you want to access an attribute from geometry produced by the HDA processor, from a TOP node? You can use a Geometry Import TOP to load a .bgeo file and load the geo attributes into work item attributes.

Thank you. I managed to get the attribute, but maybe I'm using the wrong expression or the wrong node for splitting. All streams still go on the same side.

As a result, the "filter by expression" works in my case.
