light2D half-cutted on isometric tilemap

Lbh

Hello there,

Objective

I want to successfully cast light/shadows on my tilemapped floor

Scene tree

Issue

Without the tilemap named "Floor", the light2D sprite is fine and shows the full light sprite:

However if i show the tilemap, The light is half-cutted:

The sprite upper part seems to go behind the floor:

As a beginner, i can't figure out why the sprite behaves like this.
Do you have an idea to solve this?

Thanks by advance!

Found the answer:
the mistake was that I added a normal map texture to some tiles, that were poorly created on Gimp.
When removing it, the light2D sprite is fine.

As bonus, i created a new normal map texture with the app Laigter,
you add it to your tile, and you play with 'Light2D > Range > Height' to fully show your sprite
