I do have tags set:
3D object have the tag "wall" preset in the editor.
sprite gets the tag set on create.
But lets move the 3D objects out the equation.
then i have the following sprites with physics.
Test : Get tag "wall" on created as exclusive
Player : Have no tag.
Test: Should not collide with each other BUT with player.
/ They still collide with each other, AND the player
