If you were really lazy you could do it in a single node, with scale and
all that but it would be a bit slower:
set cut_paste_input [stack 0]
version 8.0 v4
push $cut_paste_input
Group {
name Tile
selected true
xpos 297
ypos -127
addUserKnob {20 User}
addUserKnob {41 Transform T Tile.Transform}
addUserKnob {41 scale l "Scale Multiplier" T Tile.scale}
}
Input {
inputs 0
name Input1
xpos -472
ypos 2
}
Expression {
temp_name0 mx
temp_expr0 fmod((x+(width*1000)-Transform.x)*scale.w,width)
temp_name1 my
temp_expr1 fmod((y+(height*1000)-Transform.y)*scale.h,height)
expr0 r(mx,my)
expr1 g(mx,my)
expr2 b(mx,my)
channel3 {none none none -rgba.alpha}
name Tile
selected true
xpos -472
ypos 67
addUserKnob {20 User}
addUserKnob {12 Transform}
Transform {320 0}
addUserKnob {14 scale R 0 100}
scale 6.2
}
Output {
name Output1
xpos -472
ypos 142
}
end_group
