Using random dot kinematogram to create static dot array

I’m trying to create array of static dots. Basically, I’ll be presenting to boxes with dots and participants have to judge which box has more dots. I was wondering if this is something I could accomplish using the random dot kinematogram function as it would make life much easier. However, I can’t find the parameters to stop all motion. I still have dots disappearing and reappearing. Would it be better to use a code component with the elementarrystim() function? Since I will be conducting the study online, I want to limit the amount of custom coding involved in stimulus presentation. Here are the parameters I have tried out so far:

Please let me know if you have any suggestions. Thanks!
