Landscape grass culling problems and solutions

Hi i was trying to get culling working and having smooth transtition as it gets closer to the end.I saw a tutorial about per instance fade and tried it.It works but there is this another problem when i want to use culling like 20000 i started to get some square grass patches at far away.Like landscape lods were overriding my cull via preventing grass spawn even it is in culling range.So i finally managed to get it working like i want and the best thing is it is now camera dependant.I mean landscape restrictions are there but managed to find a workaround.And i just wanted to share with you in case any one need it.
