How to make line of sight visible and blocked by walls?

Hi everyone. We eventually got this working using procedural meshes and the EQS system and made a video about how it’s done. Thanks to everyone that tried to help!

Note: There were a few things in the video that weren’t quite perfect (We fumbled a node connection and forgot a to add +1 in a section) so do read the description, where we explain how to make it work perfectly. Hopefully this will help anyone who stumbles into this thread.
