How Ignore mask in collision query params work?

Here is how I use it:

FCollisionQueryParams QueryParams;
QueryParams.IgnoreMask = 1 << 3;

Now any sweep/trace that uses QueryParams will ignore any collision that has the MaskFilter = 1 << 3.

So for any primitive component subclasses that I want sweeps to ignore I set:

SetMaskFilterOnBodyInstance(1 << 3);

So If I have a Static Mesh Component, I would do:
Mesh->SetMaskFilterOnBodyInstance(1 << 3);

Now my sweeps/traces that use QueryParams will ignore Mesh.
