Could you tell me how to put in random values fo x and y (min max)? I dont know how to do it, because x y is one value....

Often work with batch load , so that would be handy...

you could use a "VALUE" node which will output a VEC2, or, you can build a VEC2 from something else, with random "inputs":

The vectors run (x, y, z, w) [the columns] The MIN is the row on top for each The MAX is the row on bottom for each

HOWEVER

Jovimetrix uses normalized coordinates (-1...1) so there is no way you will be able to use a random from -20 to 512 as an offset. You would need to calculate the normalized version of that first i.e. :

minimum: (-20 / 512) == -0.0390625 maximum: 1.0

so that would look like:

To give the random ranges of:

X == -0.0390625 -> 1.0 (-20 to 512 if your image is 512 wide) Y == -0.0390625 -> 1.0 (-20 to 512 if your image is 512 high)

Let me know if those are not the results you get.
