Convert the Input coordinates from one space to another: Input is interpreted according to Type when transformed: The input channels can be shuffled (Order) and inverted (Invert X, Invert Y, Invert Z). Also, they can be remapped to the [-1, 1] range, for instance when the input is an 8-bit map to be used as signed normal or vector displacement map. The output vector is scaled by Scale and can be set as the shading normal (Set Normal).
