How can I have the character capsules affect navigation without affecting their own navigation?

Background:
Each character in my project has a capsule for collision.

The Issue:
When a character moves using the navmesh/ai controller, they bump directly into the capsules of other character. This was resolved by using RVO avoidance. However…

my project uses the “find path to location synchronously” node to create a path for guiding the character, as well as to display a movement preview.

The second Issue:
The capsules do not affect navigation, and so the path/movement preview both pass directly through other characters

My approach:
When I toggle the “can ever affect navigation” flag on the capsules, the second issue is resolved. HOWEVER, it also breaks movement, as each path now begins in strange directions, since the moving character’s own capsule blocks movement.

How can I have the character capsules affect navigation without affecting their own navigation?
any and all advice would be greatly appreciated

You can do nothing, I think. NavMesh builds only for static objects. Each game has this problem, not only UE.

You might be able to do some workarounds like “AddMovmentInput” to your “Movement Controller” or “AIMoveTo” so when “Collision Box\Sphere\Capsule” of one character Begins Overlapping with other character they both step aside a little.
