13/5000 flag effect - Gimp 2.10.4
#1
Hello,
I turn to your community because I am trying to make an advertising banner to decorate a circuit. it is for a use of model making.
I try in vain to fool myself, but I can not! I begin...
I just came to that with the function - filter - rendering - difference cloud -
the problem is that the effect is perfect or the degradation of colors that do not go at all. I'm looking for a tutorial for that.

Luckily I came across a site where we can find flags already made with shading and wind effects. I wish I could do the same on advertisements to make banners myself.

In this picture you can see the use of flags.

I hope I can find help here. Thank you in advance, knowing that on my side, I do not have much to bring you ...

I am not sure that I understand exactly what you want. Is it something like the image below, or something different?

You might be better off using Gimp 2.10, the filters work directly on the canvas.
Maybe something like this:

I put the screenshots all-on-one so please refer: https://i.imgur.com/3hROxYq.jpg

1. Add a transparent layer on top Layer -> New Layer
2. A bit of artistic licence required, paint in some stripes for shadows.
3. Give that a good blur Filters -> Blur -> Gaussian Blur
4. Switch to the banner layer
5. The difficult one. Filters -> Map -> Displace Click on Aux 2 input, and choose the shadow layer. Break the link between horizontal and Vertical and adjust the Vertical Displacement a little.
6. Reduce the opacity of the shadow layer as required.

Might look better with slightly wavy edges, you can do that with the warp tool.

Sapristi, looks like it was taken out of some "Michel Vaillant" story.
