I created this simple patch and a script, in both of them I have no errors or warnings, but Spark AR does not give me the possibility to start the filter and it gives me this error: "Please check the patch graph and try again". Anyone know how I can fix it?
This is a know bug with Spark, hopefully it will get fixed soon. For now, try to delete your "Variables from Script" and recreate it to fix the problem. Good luck!
