Hi @youknowleft! Can you be more specific? Do you have a sample job on Pollination that you can use as an example?

Hi mostapha,  
Sorry, my sample is too complex as it is not easy to show here. I’m not sure whether only one result can be extracted one time. If I want to get all the result of parametric runs, I have to give the index manually one by one, right? As I connect pollination with my optimization control, there are always some invalid models so I don’t know exactly how many valid results I can obtain. Thus, I need a method that can automatically extract all the valid results.

Hi @youknowleft, have you seen this discussion:

> @Mostapha, I am trying to use Fly to read the results from a parameter study, as you showed in your YouTube tutorial. My goal is to display all variations in the Rhino viewport simultaneously, so I’m recording all the data I need, however there seems to be an issue: There should be 27 of each, but instead I get different numbers for each output, and a bunch of null values. I think this is because of how the cloud components take some time to get the data, during which they still fire …

Thanks, Mostapha. I’ve seen this discussion, and my problem is resolved.
