Rotate 90

Rotate 90
Transform

Rotates an image by exactly 90°, 180°, or 270°. Pixel-perfect with no interpolation.

The Rotate 90 node applied to a source image: original (left) and result (right).
Side-by-side comparison: the original image on the left and the same image after the Rotate 90 node on the right.

Because the angle is always a multiple of 90°, every pixel maps exactly to a new position, with no resampling, blurring, or anti-aliasing. Use it instead of Transform’s rotation whenever you need a quarter or half turn; Transform interpolates for arbitrary angles, which softens the image slightly.

Rotate 90 also accepts a whole texture set: every map takes the same quarter turn, and the Normal’s directions are turned with it, so the rotated Normal still describes the rotated Height.
