When doing a copy paste with a ForEachLoop node that node will not work anymore. It will just give out several errors which can’t be fixed. It works fine when replacing it with a new created node.
I encountered this while using it for a hit result array.
Hi Davision,
Can you tell us which errors you’re getting? Do they occur on compiling the Blueprint? When you first created the ForEachLoop, what array were you feeding into it? Are you feeding the same type of array into the pasted ForEachLoop node? Please grab a screenshot of your node setup (both the original ForEachLoop node and the copied/pasted node), and the errors you get from it. Thanks!
Hi Davision,
Thanks for the additional details! As I suspected, this is a known issue that has been around for a while (UE-4911), that copied/pasted ForEachLoops retained the Array input type specific to the output it was originally given. While I wouldn’t have expected it to display this same error when attaching the copied node to the same output, it shouldn’t be an issue in the 4.8 release because now copied/pasted loops do not retain any information (the Array input will be wildcard/gray). If you see the same behavior after the 4.8 release, please let us know!
