Inputs

input
rotation_map (optional) : Per-pixel rotation added to Rotation. Values are turns: 0.25 = 90°, 0.5 = 180°, 1.0 = 360°.

Parameter	Type	Default	Range	Description
`rotation` Rotation	float	0	0 to 1	Rotation in turns. 0.25 = 90°, 0.5 = 180°, 1.0 = 360°.
`normal_map_format` Normal Map Format	enum	match_graph		Normal map format: Match Graph, OpenGL (Y-up), or DirectX (Y-down). `match_graph` : Use the graph's normal format. `opengl` : Interpret normal maps with OpenGL Y-up green channel orientation. `directx` : Interpret normal maps with DirectX Y-down green channel orientation.
