I'm glad you found it, and thanks for posting the code!

I did a number of v3.7 & v3.8 renders vs yuqk renders(a) given the code 
is exposed to the, multiple crackle uses within a thread, cache bug in 
the v3.7 and v3.8 code.

V3.8 beta 2 image on top and yuqk image on the bottom.

The color distribution looks better for the 'crackle solid' base pattern 
in yuqk, but I'm unsure why. I doubt it would be cache fix related - but 
maybe? Or, maybe something else with the yuqk re-write of the crackle 
code...

Results have me wondering how old POV-Ray versions rendered the scene, 
but I don't have any old compiles handy and no more time to play...

In any case, cool code!

(a) - I used 'crackle solid scale 0.3' for the base in the images attached.
