How to make Trace-able actor but actor does not block anything

My main character drops hidden “breadcrums” that are not visible but the enemies can see them using a trace…

I just want collision for only “trace” on the “breadcrums” actor - so a “trace” can detect if hit but the “breadcrums” actor wont block anything - is that possible?

Thanks

Look into collision responses and trace channels

Great! Those links helped.
