Working on a GPU fluid simulation:

It uses multiple viewports to hold the state of the fluids velocity, pressure, and divergence. In order to add solid objects that interact with the fluid, i need to be able to draw CanvasItems from my main viewport in the velocity and pressure viewports as well. I could create a copy of every node I want to draw and then sync their positions and data through scripts, but I'm hoping there's a better way.
