Hi @Ak1nnAN,
This is roughly the logic you’ll want:
Here, the animation timeline is a simple 0-1, though you can adjust the timing as you wish.
I would suggest though that instead of using a dynamic material instance, you use a material parameter collection. This will allow you to have one global day/night effect control which you can use in multiple materials / material instances. This will make it so you don’t need to reference all of your materials with the glyphs, and will add some future-proofing in the case that you wanted to add more day / night effects.
Here is a video explaining how to set up material parameter collections:
