Hello,

I'm a french guy, newly registered on the website.
I have finished today a Scheme script to make a multi-frames animation with falling snow effect :

Parameters allow to choose :
- frames number in the animation : 5 to 50
- delay between two frames : 40 to 100 ms
- number of flakes layers : 1 to 10
- first size of snow flakes : 1 to 10
- size difference between two layers : 1 or 2
- brush rotation : left or no or right
- direction and force of wind : -3 (strong left) to 3 (strong right)
- blur level applied on snow layer : 0 to 5
- rainy blur effect level : 0 to 20
- opacity of snow flakes : 1 to 100
- snow flakes layer display mode : 28 modes

Falling snow effect can also be applied on selected parts.
Animation display automatically open in the end of script to show what it looks like.

To create a windy rain using 5 frames, or peacefull falling snow on 50 frames, have fun with all the combinations proposed.

Good game.

Hello Wallace,

Thanks for your welcome.

I already know the GIMP Animated Snowfall Script made by Fencepost and wasn't happy with it's results.

I have imagined another way to design snow for a very smooth animation or dynamic rain.

You'll try the script i propose and tell me what you think about.

Have fun.

Nice to meet you JimmyMarco. I'm going to have fun playing with this.

Hello,

Nice to meet you too Erisian.

Surprise me posting here your animation tests.
I can't do that for now because i'm new subscriber.

See you soon.

Hi JimmyMarco.

Welcome to the GimpChat forum.
I thought no one would write a new good script-fu (only python).
It's good to have an expert in this field in this forum.
Many possibilities and it works smoothly.

MareroQ... thanks.

Wallace, You are not the first tester having trouble with a blip in the animation.
Caused by the call of Playback Preview in the end of script... no sure.

For me, testing with and without Preview give the same result... no blip and smooth animation.
Of course, it's easy to delete last line in script or add ";" at the beginning of this line to past it in comment.

I remember the tester having blip used Gimp 2.8.14.
With the 2.10.18 version and no problem... difficult to correct a bug i don't have.

I will change the version to test if it's the Gimp version the problem.

There are a lot of possibilities to test.

Just try the rainy effect with 5 layers of little flakes, wind -2, rainy blur 15 and 8 frames... lol...

First size of flakes is too small and not seen... try higher 9 or 10.
Script has too much flakes to draw... it's very loooong.......

It's true... snow effect looks better than rain rendering.
Snow was my first goal with this script, and it's its name.

Rain effect was consequence of last update with 5 frames allowing very very little flakes.

As your picture is large, perhaps it needs longer rainy blur ? ... 20 ?
And setting Difference level 2 ?

Good test.

This is a well written script and works pretty good. I like the varying sized flakes as well as the blur. It would be great to use other objects such as leaves, maybe a leaf brush?

This is very nice effect...we call em footwraps here. But last winter was the worst during my entire time, practically snowless.
Thank you for the script and welcome, will play when I have time.

Hello,

Happy to please you designers.

A lot of work today on the script to propose you more features :

- frames number in the animation : 5 to 50
- delay between two frames : 40 to 100 ms
- number of flakes layers : 1 to 15
- first size of snow flakes : 1 to 15
- size difference between two layers : 1 or 2
- brush name : Enter name text
- brush color : Color box
- brush rotation : left...no...right
- direction and force of wind : -3 to 3
- blur level applied on snow layer : 0 to 5
- rainy blur effect level : 0 to 30
- rainy blur effect angle : -90...vertical...90
- opacity of snow flakes : 1 to 100
- snow flakes layer display mode : 28 modes
- harden the layers of flakes : TRUE or FALSE
- check animation window open at end : TRUE or FALSE

Yes... now you can choose if the animation window open at end :



And the color of what is falling :



As the script use the brush tool to draw, you can also play with the dynamics setting in tool...
"Perpective" is used in the previous animation.

The rainy blur is longer than previous and you can adapt the angle of blur.
For example :
- wind force 1 set 45°... or -45° for wind -1
- wind force 2 set 63°... or -63° for wind -2
- wind force 3 set 71° ... or -71° for wind -3

The little bug called "I don't want to be saved like that" is now fixed strongly...

Good game.
