Assume your position & choice: you are on a pay-per-use platform.

That's just taking a 2D slice of the 3D. It is not giving a valid
The OP wants to get something like Hexagon pattern, not checker.
Excepted that hexagon would be kind of 'crackle solid', not 'crackle'
alone: crackle alone would rather be like quilted, continuous variation
from center (well, according to the 'form' you use, of course; a funny
parameter of crackle to look at!).
It would probably be an easy cut-n-paste from actual 3D code to remove
the third dimension from the seed and simplify the metric computation,
Short of that, you might also try to take a slice of compressed pattern,
using a huge inversed scale factor on one axis (scale <1,1,1/9999999> ?)
Will thinks about that patch...might also be interesting to consider
variant of 'form'... or new option like solid... to get a 0-100% value
based on the actual length from center to boundary.
