Question
How can i make this transition for a 3d game? it basically appears when changing to another map. I don't know how to make this map loading system aswell oof
sounds like something you might want to use a shader for. I don’t know much about shaders but maybe you could modify this to add a raster to the characters as well, or maybe you can find a shader better suiting your needs.
As for the switching system, i would simply load the new background with the transition shader on top of the old background, then load the raster shader on the foreground objects, then load the new foreground with the transition shader and the raster shader, then load the new background on top of the old background with the transition shader on it.
You might want to addd the background and foreground to separate SubViewPorts to easily be able to apply shaders to an entire layer.
List of shaders that maybe useful

woow these look exactly what i wanted thank you! Is there a way to apply the shaders in a general way instead to apply them in every object one by one? Because it would be quite tedious to add the shader to every single item individually to work in order to work oof
sorry for the late reply, for some reason I have not recieved a notification.
As I said in my previous message You can use a SubViewport to do that. Simply make your scene child of a SubViewport and apply your shader to that.
You can make that SubViewport child of a SubViewPortContainer in order to automatically fit your SubViewport to the screen size (-:
Edit:
Actually for more complex effects this might not work.
You will probably need to do some Depth Buffer stuff (which I don’t know anything about)
But maybe this Godot 3 Tutorial is still helpful, combined with the additional steps pointed out in the Sci-Fi Scanner Pulse which I linked earlier.
