Linetrace by channel does not work

i’m very new to ue4 and i’m trying to make a linetrace work , but apparently , the line ignores a specific blurprint while it hits geometry brushes : what should i do?

When tracing on Visibility channel, the bare minimum you need to have:

  • have a collider
  • have it enabled for at least queries
  • block Visibility traces

You’re are probably missing one or more of these.
