Upload shader

Thank you for contributing to the Godot Shaders library!

Please add a title. Add a short but informative title. Since it is all shaders here, you don't have to include the word "shader".
Explain what your shader does and, if needed, instructions on how to use it.
What would this post be without the code? Please add the shader code.
for Please choose a shader type. If you are unsure of versions (GLES3, GLES2) just leave them unchecked.
Add keywords someone might search to find your shader. Separate keywords with a comma.
Choose a license to use for your code. By choosing a license you also agree to our License terms. You can read more about the different licenses and our license terms here.
Please add a cover image.
The cover image is the main image for your shader and is used in shader lists. Make sure it is informative and representing your shader in a good way. Recommended min size: 800x450px, max 2 MB.
Add up to three example screenshots of your shader. Animated gifs will work if you want to show motion. Max size: 1 MB per screenshot.
Have a tutorial or want to show the shader in motion? Provide a link to Youtube or Vimeo.
Do you have a Godot project with the shader, for example on GitHub, add a link to it.
If you have a personal site, a tutorial, itch.io page or anything else that includes the shader, add a link to it here.
