Shaders OTClient

[AnnaFeeh]

Hello Guys of OTLand

I found here on the forum even some shaders to my otclient rain, set up just right more alone than when I open OTC
and I will set up in the place that is more straight regular raining when I walk sqm to any one side (Right or Left)
for chuve is normal just found it odd that I have another shader fog and it works normal in the whole city.
