Hello, I Have use uv transform to scale a mesh UV from (0-1) to (0-8). And how could I transfer uv to make uv from (0-8) to (0-1) * 8 (looping 8 times)? Right Now if I only use attribute wrangle to tranfer uv it will not be right on the edge. Thanks!

@uv *= 8;

set texture reads to repeat mode.

main issue is that your points lay directly on uv borders
so right most points of one tile have the same u coordinate as leftmost of neighbour tile
which makes it difficult to offset correctly using point uv coordinates directly

there is man options, but the most straightforward in your case may be getting average uv per prim which will be within the uv tile for each slice and therefore you can clearly compute the offset to move them to 0-1 tile
