Nuke Expression Node

Offset Image

Use the expression node to offset pixels, for instance to make sure an image is tileable

In each channel R/G/B

r((x+offset)%width, y)
g((x+offset)%width, y)
b((x+offset)%width, y)

• r would get the red value of that pixel, equivilant to r(x, y)
• To get a different pixel r(50,245)
• offset refers to the custom variable set at the top of the node
