Shader on PE doesnt work after appliing.

I got a very nich shader for my world, and it always worked very well. It changes the sky, makes a smooth lighning and gives a effect of wind to leaves and grass. However, since the last update it only changed the sky, but all the other effects are sadly gone. I also tried some other shader, it went all the same. It lookes a lot less cool now, please fix this as fast as possible.
