Hello, I'm new to Godot so apologies for any nooby elements to my query.
I'm interested in creating or emulating an effect that I here call "infinite void hall of mirrors effect". I've seen it mostly it in the Source engine where, if you are outside the game map and looking at an area without skybox, the window fills with earlier frames of textured objects (see image).
As far as I know this comes from "the fact that the framebuffer is not cleared between frames. That is, the data from the previous frame is not deleted from the framebuffer before the next frame is drawn, so if the next frame has transparent regions, then the un-deleted data from the previous frame will show through." (https://halo.fandom.com/wiki/Hall_of_Mirrors#Explanation)
I now want to ask if anyone knows if this in any way can be done in the Godot engine? My thinking is through some kind of shader since I haven't found a way to make the default background texture-less, but that's where my knowledge ends sadly.
Thanks!
