I look at your G'MIC plugin PC, but don't follow how to pass your parameters using the GIMP gui. I tried to match your entries to the sliders, but not all the parameters makes sense to me. Could you post a screenshot of your parameters by chance (or are you using the command line for these renders; makes more sense if you are)?

But i am not using the command line, i was testing the plugin.

ok i made another test and I'll be back here.

It was just my opinion. I totally agree with your reasoning.

Btw, I am wondering if it is possible to have "Pencil Smoother Smoothness" beyond the max value of 10.0 ?

not exactly but lowering the values of the other 2 sliders may be closer as result

okay, that helps!

Ah; see how to do it now. Just save any Graphic Novel preset then edit the .fav file. Also, you copied the data wrong; you have a number with a coma and then another number. Believe below is what it should be:

old: {GN- CHIAROSCURO}{Graphic Novel FX}{gimp_photocomix_booost2}{gimp_photocomix_booost2}{1}{4.36364}{10.4727,5}{5}{20}{0.12}{14}{0}{0.54}{2.9}{9}{0}{0.93}{1}{0.5}{0.54}{0.78}

what it needs to be: {GN- CHIAROSCURO}{Graphic Novel FX}{gimp_photocomix_booost2}{gimp_photocomix_booost2}{1}{4.36364}{10.4727}{5}{20}{0.12}{14}{0}{0.54}{2.9}{9}{0}{0.93}{1}{0.5}{0.54}{0.78}

How do these presets work, anyway? I added to faves, but the preview doesn't look any different after refreshing. Just curious. (I should probably go read at Flickr).

Mahvin try this ones ,again they require the last version of the filter (out from no much hours)

you just paste the line but in your gimp.faves file

I had to close, then re-open GIMP for the changes to show Mahvin.
