What is currently the easiest way to add a post processing custom GLSL shader to the Stage?
In 2014 it was possible by using OpenGLView. Now I can’t figure that out anymore, because I can’t override the OpenGLView render function.
All the hints here in the forums did not work, at least with OpenFL 7. And I read adding custom shaders to sprites, bitmaps etc. is temporary disabled.
So I am wondering if it is really not possible to add a post processing shader over the screen/stage in OpenFL7 without going crazy?
I know how to use vertices, textures and shaders with lime/openfl, but then I don’t know how to render the framebuffer to a texture and then render that to the screen. Maybe I’ve overseen a simpler approach, so I am asking.
Something like "stage.addPostProcess(“shader.frag”).
