Ignore actors with a specified collision response from a trace

My answer from comments on original question.

If I refer to the original question that said you are using a Trace to determine where the player can move. You must be handling the “Collision” stuff on your own and only using the trace to determine if your player should “collide” or move through the object. A custom trace channel with customized default collision profiles (WorldStatic, WorldDynamic, etc) will achieve the result you desire. You can modify the Trace and Object Type responses for each profile in the editor.

Technically, you could either create a new Object Channel or Trace Channel and assign a default response. Then you go through the “Preset” collision response profiles and adjust the response to this custom channel for the defaults and any other channels you created.

Some combination of this functionality should be able to get you the desired result.

I’m sorry I don’t have a definitive answer but it’s still kind of difficult to understand exactly what you are trying to do.
