Hi Adam,

Warp By Scalar couldn’t apply to Image data directly.
So you should convert images to surfaces, and apply the warping filter.
TIFF image
-> Extract Surface
-> Warp By Scalar (or Vector)
If your images are not 1 or 3 channels (cf. includes Alpha channel),
you should extract elevation channel(s) by Calculator Filter.
