I am creating a multi-staged postprocessing effect add-on for Godot 3.0. I am using
Backbuffer-copy with a viewport to combine two stages of the pipeline together like so:
|> ‘3D scene’
|> Viewport
|> TextureRect with first postprocessing effect.
|> BackBuffer Copy
,|_> TextureRect that combines first effect with original viewport texture.
However, when I attempt to sample the viewport in the shader of the second textureRect, it always passes vec4(0.0), like the viewport has nothing in it.
This better not be a Godot bug.
