Hello,
I’m trying to follow a tutorial in order to create a BP slider that lets me change some substance designer material instances ingame. This is it: (21:05)
At this second, they split the array to see and work with other outputs. But I’m not able to do this action, getting the following message:
Any idea on how to solve this? I have little knowledge about blueprints, just need this slider for an art project.
Thank you.
Wait… Im trying to reproduce this
The tutorial is using a Single Line Trace, while you’re using a Multi Line Trace, therefore your result is an array (as you can see from the different icon). If you want to follow the tutorial, replace it with a Single Line Trace, if you specifically want to use a Multi one, then first you have to get an element of the array (for example Get(0) ), and you can split the struct on that result.
Thanks a lot, that was a noob error.
Glad it fixed it!
Please mark the answer as correct to close the issue, thanks!
