leolimasa I am getting a gray rectangle instead of the shader effect on 3.0: The shader is the exact same as the blur effect on the examples repo (https://github.com/godotengine/godot-demo-projects/tree/master/2d/screen_space_shaders). What am I missing? Looks like it's something really simple, as the demo works fine, while my project doesn't.
Megalomaniak I can't even reproduce the issue. Care to share your project file? edit: I'm guessing you don't have a placeholder texture setup in the TextureRect.
