Question by Deniz2014 · May 06, 2017 at 09:54 AM · shadertexturespritesalpha-channel

Circular Whipe Effect

Update: Solved it I am using this now: https://github.com/CiaccoDavide/Unity-UI-Polygon

I can draw an animate triangles with this.


Hi Community,

I am working on a little effect like in this oldschool intro but cant get it to work:

http://www.youtube.com/watch?v=6fQA8lp0wEg&t=0m18s

This is something I would call a radial or circular alpha whipe.

In my case the letters are sprites because they are created dynamically.

  • I tried different shaders I found but dont want to dig into CG Programming.

  • I tried animating a 3d Quads over them, which kind of works but feels like a lame solution

Do I think to complicated?

Any Input or Hint what "feature" of Unity to use would be helpful. So I dont expect a whole Solution, just a Keywored like "only with shaders", "use XY", "try approach ZZ"
