Post Process Blur Effect doesn't work

Hi everyone !

I want to make a blur effect on my screen using the post process. To do that, I followed this link

However, the result isn’t really the same. I have no difference when I put the material in the post process. :confused: I don’t really understand the code part and I don’t know if I have to do something special to apply this code (First time I using it).

I put the Material in the blendables part of the post process (and he is on the good array).

Thanks for your help :slight_smile:
