Hi bentraje,
The examples that you showed were different for each application.
It would be more clear to use the same stamp pattern in both examples.
I can’t find any manual entry for automatic pattern recognition
http://docs.pixologic.com/reference-guide/alpha/
However, I think Z-Brush has functionalities, of course, that are not available in general applications.
Anyway, Follow is the primary option for this. It certainly needs attention based on the image-pattern how other parameters are set.
My suggestion for a short pattern, instead of repeated parts in the image, was a suggestion to get what you are after.
You might check with the support if you think that is a problem.
Please make your suggestion for automatic pattern recognition.
