dF/dUV node

Access: Nodes > Math > dF/dUV

Outputs the rate of change of the input with respect to UV texture coordinates.

Note: This node will not work for displacement (it is fragment shader only).

Input (RGB)	Output (RGB)
Uniform UV mapping with flat color input	0.0, 0.0, 0.0
Balanced 2D UV gradient (U+V) matching pixel grid	2.0, 2.0, 2.0
Dynamic procedural height map on un-stretched UVs	Vector derivative map matching surface slope

dF/dUV node inputs

UV	Texture coordinate map.
Input	The signal to evaluate across UV space.

Output

The directional derivative of the input signal relative to the UV space.
