Problem with showing shadermaterial

Godot Version

4.2.2

Question

Edit ! Deleted the material and made a new one. Now it works! Obiviously there was “something” in the resource itself, dont know what.

I have spent few hours trying to set shader material from custom resource.
Everything works fine; except in the game. Material loads and works fine in editor plugin. I have tried duplicate, make local to scene, but material is without color. Materials Next pass material works and every property is readable and shows correct information. If I make a new material(same shader as resource) and pass values from the “original” to new, everything works?!? I dont have no idea why this original resource doesnt render correctly? Any toughts?
