Snow effect - Gimp 2.8 or 2.10

[Arlie]

Hello there !


I am begining with Gimp and have both 2.8 version (at work) and 2.10 (at home).
This is what I would like to do:
- I have an existing GIF created in Gimp (a sphere revolving on itself)
- I would like to add snow falling on this animation

I have tried to use a script I found online "Animatedsnow". It works on a static image but I can't find how to make it work with the animation.
Either I get an error or it simply doesn't work depending on Gimp version...

Then I tried Gim'c rain and snow effect but it looks more like rain thann snow ..

Could anybody help me please ?

Guessing that the script you have is Fencepost's   AnimatedSnow.scm I have looked around but so far that is the only one I know (apart from gmic)

This works 'as-is' in Gimp 2.8 but not in Gimp 2.10

Not working with an animation? Probably the animation is in Indexed Color Mode, Change it to RGB mode Image -> Mode -> RGB

Why does it not work in Gimp 2.10? The script uses some old standard Gimp 2.8 plugins that have been replaced in Gimp 2.10 by more up-to-date GEGL filters. 

You need these old plugins from 2.8:  blur-gauss.exe  cubism.exe  noise-randomize.exe

If you want to try with Gimp 2.10 then those are attached. Assuming your office home computer is 64 bit.

The usual, Unzip 

Put blur-gauss.exe  cubism.exe  and noise-randomize.exe in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\plug-ins

Put AnimatedSnow.scm in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\scripts

Hello Rich2005 !

Many thanks for this help !
Yes absolutely, it is Fencepost's script. I have already tried to change mode but to no avail I'm afraid.
And yes both computers are 64 bits.
I will try what you advise and will tell you how it went !

Again, many thanks and have a good day !

It could be that your gif animation is optimised and another hurdle is, if there is a transparent background.

The sequence then becomes

Open gif. Change mode to RGB
Un-optimize the gif Filters -> Animation -> Unoptimize
Apply the snow effects script.

Then it depends if there is a transparent background or not.
If no transparent background then optimize it Filters -> Animation -> Optimize for gif
Export that as a gif using the disposal method combine.

If there is a transparent background, do not optimize.
Export that as a gif using the disposal method replace.

Hello again Rich2005 !

Yeah you ! You're GREAT !
It works just fine with your tutorial and resources. Many thanks for that !

I think I misplaced the script in a folder named C:\Program Files\GIMP 2\share\gimp\2.0\scripts (I followed another tutorial) and furthermore I didn't have the additional plug-ins you provided !
I just tried in Gimp 2.10 and it is working !

Many many thanks for your help !!

Good morning, all.

I have been out of the graphics game for awhile and decided to play around today and came across the same issue as y'all.  I have figured out a workaround, but, unfortunately, the original settings don't produce the same results.  I've been experimenting all morning and am getting close but am not completely happy.  As soon as I get something I'm fairly happy with, I'll post here, but it may be a couple of weeks due to starting a new job and very rough scripting skills! LOL  I'm sorry for all the trouble, but thanks for keeping the script alive.

Cheers.  Art

Here's what I've come up with. I think it looks pretty good. What say y'all?

Hello there !
Hum, I can't see anything... :-)

Looks realistic to me.

[rich2005]

Made with gmic plugin - by hand layer-by-layer but quick to do. (accumulated snow added later) Does not optimise very well



I really must get out more.
