Cells separated by a knight's move (in chess) cannot contain the same value

The blue line is a region sums line. Digits along a line must sum to the same total in each region the line enters. If a line enters a region multiple times, each instance is calculated separately. There are 2 RS lines in this puzzle, one 9 cells long that is vertical, and one 9 cells long that is horizontal. They intersect, but do not change direction.

Cells joined by white dots are consecutive in value. Not all dots are given.

Cells joined by Vs sum to 5. Cells joined by Xs sum to 10. Not all Vs and Xs are given.

Digits along the diagonals must not repeat on their respective line. Additionally, the positive diagonal (bottom left to top right) acts as 3 unimodular lines. In each box it crosses, the 3 cells on the line must be from the same modular set, i.e.: 1,4,7; or 2,5,8; or 3,6,9. On the negative diagonal (top left to bottom right), the line also acts as renban lines. In each box it crosses, the 3 cells on the line are a 3-cell renban, which contains consecutive digits in any order.
