Hillustrative script-fu error

[Chuanist]

Dear All—

I run GIMP on two Macs, in El Capitan (Mac OS 10.11.6). I realize most GIMP users are not Mac heads...

An article on hyper-realistic photos (link is in the next paragraph) on Pixls.us really caught my interest. However, when I downloaded and installed the script to produce the frequency separation layers: hillustrative-2.8.scm, only one layer gets created in GIMP 2.9 and 2.10. Then it crashes.

See: https://pixls.us/articles/highlight-bloo...tion-look/

The script can be downloaded here: http://www.machead.info/scripts/hillustrative-2.8.scm

I wonder if  anyone has experienced this?

These events take place  upon running the Script-Fu script Hillustrative:

The Blur layer is created, then:

Error:

GIMP Message

Execution error for ‘Hillustrative’;

Error: event: unbound variable: plut-in-gmic

Upon closing this error message, another error message is revealed underneath it:

GIMP Message

‘Hillustrative’ left image undo in unbound state: closing open undo groups.
