Line trace to ignore hidden actor

How do you have a line trace ignore a hidden actor? Also, how do you do the same with a player character?

If line trace uses visibility channel, it doesnt mean that invisible object will be ignored. Its the only name of channel.

To ignore something, you must set Ignore for trace channel in object physics settings

Thank you.

HA ! the answer after an hour of being totally held up doing something else alltogether !! cheers…
