produces results like this tutorial Lightning like Zeus tutorial : http://gimpchat.com/viewtopic.php?f=23&t=14475

1. You need this following file unzipped and put it in Gimp's plug-ins folder.


2. Then this file inside Gimp's scripts folder.

The above version might conflict with an existing lightning.scm go HERE for non-conflicting version

3. Then you need to have an active path defined, and run script available under Script-Fu/Lightning like Zeus...
And it'll create 5 layers for your animation.

4. Additional script that merges lightning with your selected background image:http://gimpchat.com/viewtopic.php?f=9&t=14478&p=199454#p1994547
Or this version colorifies that lets you choose color instead of hue:http://gimpchat.com/viewtopic.php?f=9&t=14478&p=199592#p199592


You'll be given options like below



Example results:
Opened path



Closed paths

I don't know how you managed to script this, especially that quickly. Kind of appropriate that I'm first to download it.

What does the "Levels gamma" input do?

Gamma can be used to sharpen the lightning ..the lower the gamma the sharper it is but if it's too sharp then it doesn't have as much glow.

Gotcha. Looks like it still needs a bit of manual touchup afterwards. But I'm anxious to see how much time it saves.

That's weird, it isn't showing up in the menu. I opened the script in my text editor and it looks like it's registered right. But it isn't under Script-Fu or anywhere else.

restart GIMP, maybe? because of the extra .py script it uses.

Working for me, great script , thanks Trandoductin and Sasquatch, quick play as I should be somewhere else

did you extract .py file into plug-ins folder? not scripts. two files go in different folders. I don't know what else could be wrong.

Same here. Got the plug-in with all my other py-fu stuff and the script with all the other scm stuff. I even tried editing the scm with a cut/paste from another scm to change the menu location in case there was some syntax problem with the menu line of the scm. No luck.

i am really stuck here... not sure why that is.

I'm just glad it isn't only me. Could it maybe be a version issue? Wallace runs Windows, I run Linux, so it isn't an OS issue.

A long shot perhaps, but if by accident the name in the define (here lightning) is already in use in another script, and Wallace has numerous, one of the scripts won’t show.

(define (script-fu-lightning

Actually, I bet you're dead on. I had to rename another "Lightning" script to install this one. But I didn't think about the registry issue. And I just successfully installed the script on this other computer, which doesn't have any added scripts yet. Seems the problem has been solved.

Just noticed there is also difference-clouds2

(define (script-fu-difference-clouds2

unlikely but ?

Strange. I wonder why it works on one of my computers but not the other if it isn't a conflict with another "lightning" script.

Tran, does the script apply the blur to the mask as well? The edges of the result are a bit more well-defined than I would like. Other than that, I think the script does a fine job of duplicating the tutorial. I do wish there were some way of knowing what the hue setting would do ahead of time. I guess you have to kind of experiment with that a bit to see what number gives you the color you're after.
