I want to transform an image after it has been created, like the compositing Distort nodes. However, I cannot seem to find an equivalent in shader nodes. I need to transform the Color output of the Texture node.
I am trying to create a Node Group that takes a procedural image and "symmetrize" it. This basically takes one procedural image Color output as an input, cuts it in half, and combines the half with its mirror. Because I only want one procedural image input, I need to find a way to flip the Color input, and I cannot access the Vector input of the procedural image from inside the Node Group.
Is there a way to do this in Blender, or is it not possible?
