I’m new to Godot. I would like to use an image as a static background for a 3D scene with a fixed camera (in Godot 3.0). Seems like any TextureRect node get always painted on top of my 3D objects. If I use a Sprite3D node it covers the objects behind (because of depth test). Is there a simple way to put my image behind everything or to be prerendered?

you can use Viewport for it.
here is my test scene setup and script.

the texture for $"3d" node will be update automatically if 3d scene is updated.

I want to duplicate what you done in Godot 2 and attached are my settings.
However I cannot achieve what you did so whats my problem?
Thanks!
