How can I add a separate collusion layer to foot area (topdown 2d)

Godot Version

4.3.stable

Question

  • I have a Characterbody2d
  • I want to make it collide with enemies etc. with bigger collusion box (this is the normal CollusionShape2d I use)
  • I want to have a separate collusion for the foot section to walk into some isometric tiles but still collide. So this would be a smaller collusionbox

This is what I did
PlayerBody2D

  • BodyCollusionShape2d
  • StaticBody2d
    • FootAreaCollusion2d

I set the relevant maskings to make environment collide with foot only, but it doesn’t seem to work. It doesn’t seem to be using collusion on the foot at all.

How else can I setup the foot collusion?
