Platform effector 2D doesn't do anything

Unity Engine

Hi all,
I’m trying to implement a typical platform behaviour: The object could pass from below but collide from above.
Problem is, My platform effector doesn’t do s***, the collision occurs from both angles.
Here’s my object:

The TileMat makes bouncing 0, that’s all.
The view dependent generator creates collision data on every frame, based on various stuff going on in the scene. All it does is that it assigns 2 points to the edge collider.

As you see the Arc looks up, where it should be.

The object I wish to pass and collide is on layer “Player”.

NOTE I’m using EdgeCollider2D for collision.
Why doesn’t my PlatformEffector2D work?

If you modify a collider then any existing contacts are destroyed. Contacts are only generated during the fixed update and these are used to determine what should pass through the platform etc. You can always simulate the physics per-frame yourself using “Physics2D.Simulate()” understanding other consequences of doing that of course such as reduced determinism etc.
