Question
Would it be possible to stop the UV from rotating with the parent node?
I am trying to make a liquid shader, and I am wondering how to make the UV’s not rotate, because when looking up, the UV’s also rotate.

You could apply the MODEL_MATRIX in your shader to reverse some of this transform. Here’s an example from the docs, in your case try the UV instead of VERTEX.
shader_type canvas_item;
render_mode skip_vertex_transform;
void vertex() {
VERTEX = (MODEL_MATRIX * vec4(VERTEX, 0.0, 1.0)).xy;
}
