I tried that and it didn't seem very dark as it has appeared in other examples. Mine looks more like snakeskin.

I modified the original script to work, but the colors are off...

I noticed he had the option to select your own pattern, but it doesn't work, it's hard coded to use his.

This is a good moment to recall excellent plugin Metallic_Effects_009-P.py by Skinnyhouse (can replace dozens of script-fu, with very many options and preview).

Thanks MareroQ! My one concern is being able to get a decent gradient map in order to control the CNC depth cuts. I'll give it a shot.

I have been trying to replicate the plasma effect that Graechen used in his rust script. I've gotten pretty close but not completely. If that could be incorporated into Skinnyhouse's plugin, that would be awesome.

In addition, thank you to Racer-X for updating the script to work.

Edit: I'm getting closer to being able to map text just need to be able to get the rusted area larger and darker, using Skinnyhouse's Metallic Effects.

The pattern is for the text itself. The rust effect is created from "Solid Noise" and not from the pattern choice.
** I manage to Constantize the code for GIMP 2.10 from Tin Tran plugin. Please try it to see how it work for you.

Pocholo's modified version seems to work nicely. I like the rust effect this script gives.

I tested the version of Pocholo provided in post #86 and the script works fine in my version of Samj 2.10.28.

But the layer on top, "Visible", is not actually the visible product of the layers below.
If I close the visualization of this layer ("Visible"), what is visible as the sum of the other layers is another image.

I suppose:
a- After the "Visible" layer has been created, some removal is done between the layers that gave rise to it.
b- After the "Visible" layer has been created, it receives a post edit.

I would like it to be possible for the user to make adjustments to the layers generated by the script and for the new "Visible" layer to be the result of these changes. (It seems to me that this would be the real function of having these layers available there).

Below, the top result is obtained by the script in default mode, the bottom result was a change in the "Glow" layer with later addition of glow and shadows on the visible layer.

Thank you all for the contributions and updates of this script!

Hi Krikor.

Interesting insights.
However, the script doesn't use 'gimp-layer-new-from-visible' (create a new layer from what is shown in the image).
Coincidentally (or maybe on purpose - because it is a top layer - but not new from visible) Graechan called the new layer (gimp-layer-new) "Visible" (lines 185 and 208), when it would be better, for example, "Rusted".

I concur with MareroQ, there is not a "gimp-layer-new-from-visible" it was a copy and paste to a New layer. The only thing I did to the script was to replace all occurrences of old constant names, with GIMP 10 constant names. I did only one change on the "plasma layer" in line 132, changed the layer mode from NORMAL- MODE to "LAYER-MODE-GRAIN-MERGE-LEGACY" and it gave a better real look at the rust.

Hi MareroQ,
My assumption was a sophistical syllogism that could have been avoided.
Thanks for the clarifications.


The script makes it a lot easier to get this kind of rusty effect, thanks for updating it!

Well, is not new just modified for a little more realistic color look. It's still Graechan script, he was the creator.
