The tracing blueprint APIs have a boolean input named “Trace Complex”. After searching I haven’t found any explanation of how this flag affects the tracing results.
The standards docs have no documentation for this. For example:
I found some questions mentioning this term, but they didn’t help explain it well either.
Any idea?
I believe that trace complex is a polygon based trace where as the basic is collision based. So if you have a character with pill the shaped collision thing, the trace will hit that. So you won’t be able to trace between their feet, arms etc, but complex will look for the actual mesh. Might need someone to confirm this though.
This is correct
