I currently have a setup where i draw 2 little gradient balls, one is in the root of the game, and the other one is within a Viewport node.
I use a sprite node to render the Viewport texture, but this is the final result:

The red ball is the one inside the Viewport, and the Blue one is outside
is there any configuration i forgot to make when using Viewports?
Thanks in advance!
EDIT: I have already changed the viewport Size, but that doesn't affect the overall result
