Do custom trace channels on a Landscape work for anyone else past an editor restart?
I add a custom trace channel called “Landscape”, setting the default to “Ignore”. Then I change my Landscape’s Collision Preset and set it to “Custom…” and check “Block” for my new “Landscape” trace channel. I have a Line Trace with the Trace Channel set to “Landscape” in a construction script on an Actor Blueprint. If I set the Draw Debug Type to “For Duration” and move around the object in the editor, the hits and debug strings I added appear correctly. Then I restart the editor and now the construction script’s Line Trace will no longer hit the Landscape. I can find no way to make it work again, except to delete the channel, reset everything, then add a new one which only works until the editor is restarted and stops working again.
It works fine with Static Meshes on the new trace channel after restarts, the issue seems to be specific to Landscapes.
