output
The normals in the baked sphere image get rotated by the normals in the checker image. The effect of the rotation starts at 40 degrees and finishes at 50 degrees.
On the left toolbar choose 3D Nodes > Blend Normal. >
Drag the Blend Normal icon into the Node Graph.
Connect the output of an image node into the Img input in the Blend Normal node.
Connect the output of an image node into the Rot input in the Blend Normal node.
Adjust the attributes of the Blend Normal node to modify the blending of the two normal images.
Img
An image in Normal Color Mode.
Rot

Mask
An image in Color Color Mode that will be used for masking zones in the input image and preventing them to get modified.
Img
An image in Normal Color Mode with final result.
Multiply
Multiplies the output angle by the given value, increasing or decreasing the strenght of the normal.
Angle Start
Angle on the Img input image at which the perturbation starts.
Angle End
Angle on the Img input image at which the perturbation ends.
