Using Adjacency with the grunges/2D textures

Using adjacency with 3D noises is great - was wondering how to wire up a way of using adjacency to get seamless wrapping of 2D images, or the grunge presets.
I thought I'd be able to sample the adjacent_uv and use that to sample the image, but it's not giving the expected result, I'm getting breaks across the UV islands.
Hopefully it's something simple I'm missing! Cheers - C

Probably a simpler setup is to unpack the adjacency cable, but that also has seams:

Unfortunately, this does not magically tile 2d images. It allows you to build 2d effects that are tiled by transferring data across the seam so it is consistent. This is how the 3d noises work (as it can get the right values for other side of the seam rather than guessing from extrapolation). And how things like reactive diffusion and distort can work by looking across the seam when acting.

Ah gotcha - I thought it had some clever way of re-sampling 2d textures across UV islands - but yeah thinking about it that does seem a bit of a stretch! Thanks :-)
