here are the images for what I'm getting, Blur2 doesn't seem to work:
maybe I did something wrong?
Blur2's Viewport should also contain a TextureRect. It should display the ViewportTexture that is produced by Blur1's Viewport.
So the order of operations would be something like:
The alternative is to have nested viewports (Blur1's ViewportContainer is a child of Blur2, and you use the ViewportContainers to blur.)
I see. my bad I misunderstood the instructions, thank you
